Blackthorn are our Corporate Finance advisors and advised us on SSE Airtricity’s acquisition of a 40% stake in our company. They ensured that we were well structured from the outset and managed the acquisition process from start to finish. They were on hand at all times throughout the period and their expertise and understanding of the process was invaluable. We continue to work with them and would highly recommend them if you are thinking of selling your business.
