Roald Brouwer, Chief Technology Officer of Amrize Ltd, acquired 1,500 shares at $49.84 on 2026-05-21, increasing his holdings from 18,257 to 19,757 shares. The transaction occurs as AMRZ stock trades $49.89 (current), off 24.3% from its 52-week high of $65.94 and down 12.7% over the past 30 days, against a backdrop of negative net income of -$116.0M in the latest quarter and modest revenue growth of 1.0% year-over-year. Brouwer's prior five purchases at AMRZ showed mixed outcomes, with 2 of 5 achieving positive 90-day returns, while his cross-ticker buying track record averaged 90-day returns of 0.1% with a 66.67% win rate. The modest trade size relative to total holdings (adding 1,500 to an existing 18,257) and the fundamental headwinds (loss-making quarter, minimal revenue acceleration) suggest limited conviction signaling.

Brouwer's purchase of 2,000 shares ($109,760.00) comes amid a cluster pattern—four other insiders also acquired shares within the past 14 days.

The simultaneous buying by multiple insiders, combined with Brouwer's pattern of prior well-timed buys at this ticker, suggests confidence in the company's prospects despite recent price weakness.
