Sienna Investment Managers announces the acquisition of Acofi Gestion

Acofi Gestion to become Sienna Private Credit

Acofi Gestion becomes Sienna Private Credit, the specialized branch of Sienna Investment Managers for the alternative financing of real assets, which covers in particular corporate private debt as well as real estate and energy transition financing.

Sienna Private Credit has been developing an extensive range of loan funds since 2012 and now has around twenty funds on its various themes. The company is committed to an ambitious sustainability trajectory with the recent creation of several funds with a strong ESG impact.

For Sienna Investment Managers, this new step is part of its ambition to become one of the European leaders in alternative management and real assets, by enabling it to complete its existing offer in an asset class experiencing strong growth thanks to the proven expertise of a recognized team.

Sienna Private Credit will benefit from all the synergies developed by the Sienna platform, particularly in terms of the marketing of cross-functional offers and operational services, as well as the complementarity of the client networks of the other branches of Sienna Investment Managers.

The organization of Sienna Private Credit is not affected by the change of majority shareholder.

On the strength of its values, the company has reinforced means to design and manage innovative investment solutions for its institutional clients.

Thibault de Saint Priest, CEO of Sienna Private Credit, said: "Private debt, an asset class that is now fully recognized in the investment landscape, is set to represent a growing share of the allocations of institutional investors as well as individual customers. Becoming part of Sienna Investment Managers is a powerful factor in accelerating our initiatives in continental Europe."

Pedro-Antonio Arias, CEO of Sienna Investment Managers, declares: "The acquisition of Acofi Gestion allows us to increase our management capacities in France in private markets and, moreover, with a recognized player with whom we share common values."
