Matt Sassone, new CEO of Tristel plc

Matt Sassone, incoming CEO of Tristel, commented: "I am deeply honoured to join Tristel as its new Chief Executive Officer. Tristel has a well-earned reputation for innovation and excellence in infection prevention, and I look forward to leading this exceptional business. My focus will be on building on Paul Swinney's strong foundation, capturing global opportunities, and expanding our presence in key markets like North America. Together, we will continue to drive growth and deliver exceptional value to our customers and stakeholders."

Paul Swinney, Founder and out-going CEO of Tristel, commented: "I am excited to hand the reins of this marvellous company to Matt. We have become the global market leader in manual high-level disinfection of medical devices and now have a foothold in the world's largest healthcare market. Matt's first-hand experience of North America will propel us to great success there.

"In our time on AIM we have succeeded in increasing our share price by almost 12 times and have returned over 75 pence per share in dividends to our shareholders. I think we have created a great UK success story.

"I have had the great pleasure to work with an exceptionally talented and committed team at Tristel, who I am sure will provide their new CEO the same level of support and assistance that I have received. In the coming months I will leave Tristel in excellent shape, very well led, and as an enthusiastic shareholder of the Company.

Bruno Holthof, Chair of Tristel, commented: "We are very pleased Matt is joining as our new CEO. His understanding of the AIM market, the global medical device industry and the American healthcare market will enable the Company to continue its growth drive. He will be supported by a committed senior management team that has built Tristel over its 20 years as a public company. The Board is confident that fusing the energy of new leadership with the organisation's remarkable domain knowledge of the infection prevention market will secure Tristel's continuing success.

"On behalf of the Board, the wider team at Tristel, and all of the shareholders in Tristel over the years, I would like to thank Paul for his leadership and stewardship. Paul has built a world-class business based on our unique biocidal chemistry formulation; he has brought together an outstanding team with the energy and ambition to deliver further success; and he has delivered significant value to shareholders. Paul should be rightly proud of his legacy, having created a successful and globally-recognised infection prevention business that is making a significant difference to patients and health facilities around the world."
