Major European investor in Arqit sees ‘exciting momentum’ in new Cyber Encryption Technology

May 12, 2021

Monaco’s Heritage Group has today confirmed a major strategic investment in Arqit Limited, the British-based, UK Government funded quantum encryption business.  Heritage Group (“Heritage”) is an industrial investor with particular strength in commercial and technology businesses.  It was also a co-founder in Centricus Acquisition Corp. (“Centricus”), which has announced its intention to combine with Arqit with a pro forma enterprise value of up to $1.4 billion.  Heritage, which is managed by Manfredi Lefebvre, has also made a significant investment in the PIPE transaction that forms part of Arqit’s agreement with Centricus Acquisition Corp., joining other industrial investors such as Virgin Orbit and Sumitomo Corporation of Japan.

Heritage chairman Manfredi Lefebvre said: ‘Our investment in Centricus led to the Arqit opportunity and I am convinced this is a business with global importance and enormous potential.  In fact we followed on with a further very significant investment of our own and we look forward to bringing Arqit’s technology and knowhow to a host of partners in our region.  The momentum and opportunities here are truly exciting.’

Arqit Founder and Chairman David Williams: ‘The funds we are raising via Heritage, Centricus and other marquee investors will give us the ability to ramp up at speed and globally, to grow our business. With a new product launch in June and partnership agreements being signed – with the likes of BT, Northrop Grumman and Sumitomo – almost daily, Heritage has given us a platform for turbo-charged performance and growth and we look forward to benefitting from their long standing and deep relationships with relevant target customers around Europe and especially in Italy.’

Heritage Group is a diversified multi-billion dollar investor which has recently taken large ownership positions in businesses such as: Bucksense, Trained Theraputix Discovery and Vdyne.

Heritage’s most noted investment was Silversea Cruises, the family company founded by Manfredi’s Lefebvre’s father in 1994, transforming it into the most successful luxury cruise line in the world, with a majority stake sold to Royal Caribbean in summer 2018 at an enterprise value of over $2 billion. More recent travel industry investments have included luxury travel company Abercrombie and Kent, as well as Cox & Kings, a long-established global travel business.

Heritage recently has made further investments in technology, medical and luxury goods.
