Update on the Review of Strategic Options

Clean Air Power (AIM: CAP), the global leader in the development and delivery of compression-ignited natural gas systems and software for heavy duty vehicles, today provides an update on the review of the Group's strategic options announced on 23^rd June 2015 that is being led by KPMG Corporate Finance, as announced on 26^th June 2015.

In response to KPMG's work to secure the long term financial stability of the Group, a number of parties have expressed an interest in acquiring all or a part of the Group. Such interest may or may not lead to an offer being made for all or a part of the Group. The Board, as advised by KPMG, are in the process of evaluating these expressions of interest as a way to provide long term financial stability and maximise the value of the Group within the constraints of the Group's current financial position.

John Pettitt, Chief Executive of Clean Air Power, said: "As we explained in our announcement on 23^rd June, the decision by our partner on the South East Asian MicroPilot program to extend the first phase rather than proceed to the second and full production phase, as we had expected, has put pressure on the Group's short term cash flows; a position which has been exacerbated by falling oil prices impacting sales of our Genesis-EDGE products in the US and Russia. KPMG have been extensive in their work to secure the long term financial stability of the Group and we will continue to work with KPMG over the next few weeks to deliver the best solution for all stakeholders, recognising that the Group's short term financial position may act as a constraint on our ability to maximise the value of the Group."
