Amrize Ltd 8-K filed 2026-09-11

Amrize Ltd (CIK 2035989), a large accelerated filer trading as AMRZ on the NYSE with an SEC industry classification of "Cement, Hydraulic" and formerly named Evertect AG, filed this Form 8-K on 2026-09-11. It reports a change in who runs its Building Envelope business under Item 5.02 and furnishes the related press release as Exhibit 99.1 under Item 7.01. The filing is signed by Denise Singleton, Chief Legal Officer and Corporate Secretary. On September 6, 2026, Jake Gosa, President, Building Envelope, told the company of the decision to resign. That notice started a 12-month termination notice period under the employment agreement, which runs until September 6, 2027, and Jake Gosa remains an employee during that time. On September 11, 2026, the Board of Directors appointed Mario Gross to replace Jake Gosa as President, Building Envelope, effective the same day. The press release says Jake Gosa is stepping down and is committed to a smooth transition. For a reader tracking the leadership bench, the successor comes from inside the company. Mario Gross has been a member of the Executive Committee as Chief Supply Chain Officer since the company's NYSE listing in June 2025. Before that, Mario Gross was Chief Operating Officer of the Building Envelope business from 2024 to 2025, and earlier held commercial and operational roles at Holcim and Sika. The release describes the segment as covering commercial and residential roofing, weatherproofing and insulation systems, and gives company-wide revenue of $11.8 billion in 2025. It also includes a statement from Chairman and CEO Jan Jenisch thanking Jake Gosa. Several things a reader would want are not in the filing. It gives no reason for the resignation and no compensation terms for Mario Gross. It does not describe Jake Gosa's duties during the notice period or any severance. It does not say who will take over as Chief Supply Chain Officer, and it gives no financial figures for the Building Envelope segment.
