RETIREMENT OF CHIEF EXECUTIVE OFFICER

Diploma PLC, the international group of businesses supplying specialised technical products and services, today announces that Bruce Thompson has informed the Board that he plans to retire as Chief Executive Officer before the end of September 2018. The notice given ensures that there is sufficient time to allow a thorough search process to take place and a smooth transition of responsibilities.

Bruce Thompson joined the Group in 1994 as Group Director of Diploma's Electronics Division. He was appointed Chief Executive Officer in 1996 and led a major restructuring of the Group, divesting the three traditional core businesses, returning cash to shareholders and re-focusing the Group. Since emerging from this restructuring in the early 2000's, the Group has followed a consistent strategy, building larger, broader based businesses in its chosen sectors by combining steady GDP-plus organic growth compounded by carefully selected value-enhancing acquisitions. Over the last 15 years, the Group has delivered strong double-digit growth in earnings, dividends and share price and has grown market capitalisation from ca. £60m to ca. £1.2bn.

John Nicholas, Chairman of Diploma PLC, commented: "Bruce has been an outstanding leader of Diploma PLC during his 21 years as Chief Executive. The Group has gone from strength to strength under his careful stewardship and Bruce will continue to provide strong leadership for the Group over the coming financial year, as the Group manages the transition to new leadership, while continuing to deliver its consistent strategy."

Bruce Thompson said: "I am very confident that I will be leaving the Group with a clearly defined and sustainable strategy with a substantial runway for further growth. I am also very pleased that the Group has in place a strong and experienced senior management team to deliver this strategy under the Group's future leadership."

These essential values ensure that decisions are made close to the customer and that the businesses are agile and responsive to changes in the market and the competitive environment.

The Group employs ca. 1,700 employees and its principal operating businesses are located in the UK, Northern Europe, North America and Australia.
