June 1 (Reuters) - West Pharmaceutical WST.N said on Monday it appointed former Thermo Fisher Scientific TMO.N executive Michel Lagarde as its top boss, effective August 31, succeeding longtime chief Eric Green.

• Green, who has led the medical equipment ​maker since 2015 and became board chair in 2022, had said in March he would step down once a successor was found.

• Lagarde most recently served as chief operating officer at Thermo, with responsibility for the majority of the company's businesses.

• He joined Thermo Fisher in 2017 through its acquisition of Patheon, where he had served as president and chief operating officer.

• Lagarde will also join West Pharma's board, while lead independent director Robert Friel will become board chair as part of the transition.

• "We think Michel Lagarde checks all of the boxes in terms of qualifications that WST was looking for in a new leader with flying colors," Evercore ISI analyst Daniel Markowitz said.

• West Pharma said last month it had ​restored operations across its sites after a cybersecurity attack and expects the incident to have no material impact on its 2026 financial outlook.
