West Pharmaceutical: CEO Eric Green to retire once successor is hired; guidance reaffirmed

Neutral Impact 4 of 5 leadership Written later

CEO Eric Green told the Board on March 6, 2026 that he intends to retire as President, Chief Executive Officer and Chair once a successor is hired. The Board is engaging an executive recruiting firm and expects the transition in the second half of 2026. The company also reaffirmed its 2026 financial guidance from its February 12, 2026 earnings release, which matters to shareholders because it is a leadership change at the top of the company with no change to the outlook.
