Plant Impact plc (AIM: PIM), an agricultural bioscience company that develops and markets crop enhancement and specialty nutrition products, announces the following non-executive Board changes.

Chris Tyler has been appointed as an Independent Non-Executive Director with effect from 1 May 2015. Chris is currently the Group Finance Director at Porvair plc (LON: PRV), a specialist filtration and environmental technology business, a position he has held since 2004. During Chris' tenure, Porvair has achieved significant international growth, both organically and through acquisition. Previously, he held a number of senior financial positions at Cable & Wireless, including Director of Investor Relations and Chief Financial Officer of Cable & Wireless in the Caribbean. He is a Chartered Accountant having spent his early career with Deloitte. Chris holds a BSc in Engineering from the University of Exeter. Apart from the information disclosed in Appendix 1 to this announcement there is no further information to be disclosed pursuant to Schedule Two Part (g) of the AIM Rules for Companies.

The Company also announces that after ten years as a Non-Executive Director and former Chairman of Plant Impact, Martin Robinson will retire from the Board on 31 July 2015. Martin guided the listing of the Company on the AIM exchange in 2006 and supported Plant Impact through its recent period of strategic refocus, revenue growth and profitability. The Company and the Board wish to express its deepest gratitude for Martin's considerable contribution and leadership over this period. Martin will continue to remain as a non-voting Board Observer through 31 December 2015. Effective 1 August 2015, Chris Tyler will assume the role of Chairman of the Board's Audit Committee.

David Jones, Chairman of Plant Impact commented:

"I am delighted that Chris Tyler has agreed to serve as a Non-Executive Director of Plant Impact. The Company is fortunate to attract an experienced finance professional of Chris' quality to support its commitment to sound corporate governance. His strategic and financial stewardship of Porvair's growth offers our Company many lessons for our own expansion plans.

On a personal note, I should like to thank Martin for his long service at Plant Impact. In particular, I am grateful for his considerable support to me in 2011 in achieving the fundamental restructuring and redirection of the Company and also subsequently for his valuable judgement as a Board member during the successful translation of those changes into operational success under the leadership of John Brubaker."
