Directorate Change

Halma PLC 1 March 2005 Halma p.l.c. Board Changes Halma, the leading safety and environmental technology group, announces the appointment of Andrew Williams as Chief Executive and the retirement of Stephen O'Shea with effect from 28 February 2005. Andrew was appointed Deputy Chief Executive in November 2004 and has worked alongside Stephen O'Shea since that time to ensure a smooth transition to becoming CEO. This timing enables Andrew to close out this financial year and clearly assume responsibility for both the budgeting and the performance of the coming financial year. Andrew Williams was appointed to the Board in July 2004 having joined Halma in 1994. He has been very successful within the Group both as an operating company Managing Director and as a Divisional Chief Executive. Andrew was responsible for the acquisition of Ocean Optics Inc., an excellent recent addition to the Group, as well as playing a significant role in the development of people right across Halma. Commenting on the changes, Chairman Geoff Unwin said, 'Following an extensive evaluation process, I am delighted that an internal candidate demonstrated the strongest leadership potential. The Board and I are confident that Andrew will build on the excellent platform that Stephen O'Shea has nurtured and that Andrew will continue to encourage growth and innovation across the Group. 'Stephen O'Shea's retirement marks another milestone in the history of Halma. Stephen joined the Group in 1983 with Halma's purchase of Apollo Fire Detectors Limited where he was Managing Director. Stephen was promoted up through the ranks, ultimately being appointed Chief Executive in 1995. The Board and I wish to record our thanks to Stephen for his strong leadership over the past 10 years. Impressively, during Stephen's tenure, the Group's turnover has doubled and headline profits have grown from £29 million to over £50 million.' Halma today is capitalised at approximately £600 million, and the Group is widely recognised for its ability to create wealth for its shareholders and for its consistently high returns on capital employed. Halma's trading statement relating to the year ending 2 April 2005 will be issued as usual in late April 2005.
