Sienna Investment Managers in exclusive negotiations to acquire Acofi

Sienna Investment Managers ("Sienna") and Acofi Gestion have entered into exclusive negotiations to acquire Acofi from certain of its current shareholders (La Française Group and non-executive partners). Following this transaction, Sienna would be the sole controlling shareholder of Acofi.

Acofi will add further expertise in the financing of real assets to Sienna, in particular corporate, real estate and renewable energy private debt. There will also be synergies as Acura benefits from Sienna's European network and the support of GBL as a strategic sponsor.

This acquisition will be another step in the development of Sienna's strategy of building a European leader in alternative asset management, adding further strands to its existing offering in this fast growing asset class. The current offering comprises real estate and private equity (directly and through funds of funds) as well as in liquid asset management (subject to the completion of the MH GA acquisition).

Thibault de Saint Priest, CEO of Acofi, said, "We're excited to be joining Sienna's multi-strategy platform, which has a powerful momentum and a strong growth strategy. This new step will allow the Acofi team to expand its private debt fund offering while further improving the quality of service provided to investors, thus extending the work already done in the area of direct financing of the economy."

Pedro-Antonio Arias, CEO of Sienna Investment Managers, added, "We are bringing together alternative asset managers with different specialisms - experts in their fields. This will see us integrating their offerings into a global alternative platform, offering exposure to these attractive asset classes in the form and structure investors prefer."
