Ark Therapeutics Group plc

Ark Therapeutics Group plc is a specialist healthcare group (the "Group") addressing high value areas of unmet medical need within vascular disease and cancer. These are large and growing markets, where opportunities exist for effective new products to generate significant revenues.

Ark has an early stage pipeline emanating from collaborations with University College, London and the AI Virtanen Institute in Kuopio, Finland, the development of which it intends to progress in collaboration with pharmaceutical and biotech partners.

In addition Ark has the ability to off-set a proportion of its R&D costs and to generate sustainable revenues through the exploitation of its proprietary technology platform, process development, scale-up and manufacturing capabilities on behalf of third parties.

Ark has its origins in businesses established in the mid-1990s by Professor John Martin of University College London and Professor Seppo Ylä-Herttuala of the AI Virtanen Institute at the University of Kuopio, Finland, both of whom remain consultants on the Company's research and development programmes.

Ark's shares were first listed on the London Stock Exchange in March 2004 (AKT.L).
