Shares of Amrize Inc. (NYSE: AMRZ) declined 3.9% in after-hours trading on Monday after the company announced the departure of Chief Financial Officer Baris Oran, effective immediately.
The company named Samuel J. Poletti as Oran’s successor, effective August 24, 2026. Poletti, who previously served as Director of Strategy and Mergers & Acquisitions at Amrize since its New York listing in June 2025, will be based at the company’s operational headquarters in Chicago. In a statement, Chairman and CEO Jan Jenisch praised Poletti’s leadership, highlighting his role in the company’s spin-off process and subsequent value-creating transactions.
Poletti brings over two decades of experience from Holcim, where he managed transformational acquisitions in the Building Envelope segment, doubling the business’s size in North America. His appointment follows the company’s recent leadership adjustments, including the addition of Dillon Cumming as Vice President of Investor Relations, effective September 8, 2026. Cumming previously held roles at Walleye Capital and Morgan Stanley, where he led financial and strategic analysis for the Industrials sector and covered building materials companies.
Amrize, which listed on the New York Stock Exchange in June 2025, has not provided updated guidance or commentary on the leadership change beyond the personnel announcement.
