The deal, subject to regulatory approval, comes as part of a strategic partnership between the hospitality groups and also sees the launch of not-for-profit initiative Community Conservation Fund Africa (CCFA) to protect African wildlife.

Its creation brings together three conservation organisations – Wilderness Foundation, Tusk Trust and African Parks.

Mantis’s portfolio of 28 managed properties includes boutique hotels, eco lodges, game reserves and luxury houseboats.

The group also boasts a bespoke tour operating division.

Accor said taking a stake in Mantis “reinforces” its position as “a leader in curated one-of-a-kind experiences”.

Sebastien Bazin, chairman and chief executive of Accor, said: “Mantis is a pioneer in customised one-of-a-kind travel services in some of the most imaginative hotels across the world.

“With this strategic partnership, we are reinforcing the group’s footprint in Africa and we have access to a brand with strong roots and heritage, recognised for its commitment to preserve the environment and its prestigious credentials in the hospitality space.”

Adrian Gardiner, founder and chairman of the Mantis Group, added: “Accor is one of the fastest growing hotel and travel operators worldwide.

“This agreement presents an attractive proposition for the Mantis Group to utilise AccorHotels’ robust distribution channels and world-wide reach to further develop the hospitality concepts and sustainability projects we have worked so tirelessly to grow.

“We are excited to embark upon this new chapter alongside AccorHotels where we will act as ambassadors for the development of both our Groups’ portfolios and offerings.”
