Mario Gross, Chief Supply Chain Officer at Amrize Ltd, filed 3 separate purchases totaling 4,000 shares for $196,032.00 at a blended average price of $49.01, raising his post-transaction holdings to 34,747 shares from a pre-transaction level of 30,747 shares. The purchases arrive as AMRZ shares sit -24.3% from their 52-week high and have declined -12.7% over the past 30 days and -23.4% over the past 90 days. Notably, 2 other insiders also bought within the past 14 days, forming a cluster buy pattern that broadens the signal beyond a single executive. In his prior trades at AMRZ specifically, 3 of 5 prior buys were well-timed at the 90-day mark, though his two most recent AMRZ buys in March 2026 each saw negative 90-day returns of -9.7% and -9.3% respectively.

Gross Mario, Chief Supply Chain Officer, executed two separate purchases totaling 3,200 shares for $176,936.00 at a blended average price of $55.29 on March 13, 2026, increasing his holdings by 11.5% to 30,947 shares. This transaction is noteworthy because it occurs within a cluster of 4 other insider buys at AMRZ in the past 14 days, suggesting coordinated accumulation across the executive suite. Mario's same-ticker history shows 3 prior buys in August 2025, all of which posted positive 90-day returns (ranging from +0.2% to +6.3%), indicating consistent timing accuracy at this ticker. At the current price of $56.35, the stock is -14.4% from its 52-week high and -4.2% over the past 30 days, positioning this buy near a relative weakness in a stock that has still delivered +1.7% over 90 days.

Chief Supply Chain Officer Mario Gross bought 3,000 shares at $49.63 on 2025-08-13; 6 other insiders also bought within 14 days.

Gross Mario, Chief Supply Chain Officer, purchased 3,000 shares at $49.63 on 2025-08-13, adding to his position of 20,232 shares and increasing holdings by 14.8%. This buy occurred within a cluster period: 6 other insiders at Amrize Ltd also acquired shares within the preceding 14 days, suggesting coordinated or independently aligned insider confidence in the company's near-term prospects. The transaction price of $49.63 sits 3.4% below the current market price of $51.48 and 6.3% below the 52-week high of $53.00, positioning the purchase in the middle range of recent trading activity. While Gross has a track record of 2 prior open-market buys across other tickers, his AMRZ-specific activity shows 2 recent purchases (2025-08-11 and 2025-08-08) that lack measurable 90-day outcomes. The cluster buy pattern and repetition of purchases within a short window merit monitoring to assess whether this reflects informed conviction or external strategic considerations.

CSCO Chief Supply Chain Officer buys 7,600 shares (2 transactions, $358.0K) as 6 insiders buy within 14 days

Gross Mario, Chief Supply Chain Officer at Amrize Ltd, executed two purchases totaling 7,600 shares for $358,050.00 on 2025-08-08 and 2025-08-11 at blended average price of $47.11, expanding his holdings from 12,632 to 20,232 shares (+60.2%). The transactions occur as 6 other insiders also bought within the past 14 days, forming a notable cluster purchase pattern. Current price of $48.57 sits -8.4% from the 52-week high of $53.00, and the company trades within its 52-week range ($46.65–$53.00), suggesting neither extreme valuation nor distress at the time of purchase. The synchronized buying activity across multiple executives merits observation as a potential indicator of internal confidence, though the pattern itself remains a factual cluster without additional context on management's strategic outlook.
