West Pharmaceutical Services CEO Eric Green said on Monday that he plans to retire once the company appoints a successor, bringing his 11-year tenure at the helm to an end.
The Pennsylvania-based company added that the leadership transition is expected to take place in the second half of 2026, and that an executive search firm has been engaged to lead the process.
“After serving 11 years as the Company’s 6th CEO over the past century, it is time for someone else to take over the leadership of West,” Green said in a statement.
Eric Green, who became CEO of West Pharmaceutical Services in 2015 and was appointed board chair in 2022, said the decision will allow him to focus on future board and advisory roles.

During his leadership, the company more than doubled its revenue and generated a total shareholder return of about 350%, according to lead independent director Robert Friel.
West, which manufactures components and delivery devices used for injectable medicines such as diabetes and obesity treatments, said last month that demand for GLP-1 therapies is expected to keep rising in 2026, although at a slower pace than in 2025.
GLP-1 drugs have emerged as one of the fastest-growing segments in the pharmaceutical market, increasing the need for the precision drug-delivery components supplied by West.
