Insights

TL;DR: Officer Poletti purchased 1,280 AMRZ shares on 08/08/2025 at CHF 37.37 (USD $46.22), raising direct holdings to 3,389 shares.

The transaction is clearly documented with price, currency conversion and post-transaction beneficial ownership. The filing does not provide outstanding share count or percentage ownership, so the purchase's scale relative to the company cannot be assessed from this Form 4 alone. The use of an Attorney-in-Fact signature is noted and the filing was made by a single reporting person.

TL;DR: Officer-level insider executed a direct purchase; documentation includes exchange-rate explanation and post-transaction holdings.

The Form 4 documents an officer purchase and identifies the reporting person and title. The explanatory note specifies the transaction currency (CHF) and the conversion rate used, which improves transparency. The filing contains no mention of a pre-arranged trading plan or derivative transactions. Materiality for governance or control implications cannot be determined from the disclosed share counts alone.
