Company Update

London, UK, 5 July 2013 - Ark Therapeutics Group plc (LSE: AKT) ("Ark") has been notified by Crawford Healthcare Ltd ("Crawford") that it is of the view that certain sales of its products (KerraMax Care) do not constitute relevant sales for the purposes of the earn-out consideration due to Ark (subject to certain revenue targets) under the sale agreement dated 7 February 2011 pursuant to which Ark's woundcare business was sold to Crawford Woundcare Limited. As such, in Crawford's view it is unlikely that the revenue targets will be met in respect of calendar year 2013. Ark strongly disagrees with the position Crawford is attempting to assert and, having taken legal advice, is confident that the product sales in question should be included in the relevant revenue targets which may or may not trigger earn-out consideration. Whilst any payment to Ark of deferred consideration remains subject to the agreed revenue targets being met in calendar year 2013, and as such no guarantee can be given as to the likelihood of those targets being met, Ark is confident that on the basis of advice its position is sound and it will take all steps available to it to protect its contractual rights.

Non-Executive Director, David Venables, comments:

"We were initially contacted by Crawford Healthcare to discuss their position in April and since then the Company has taken independent legal advice on the detail of the contract. Discussions continue, and we hope to resolve the matter amicably with Crawford Healthcare."

A further update will be provided in due course.
