A Focused Activity

Callisto assists and advises management teams in the preparation, structuring and implementation of a Buy-Out. Its mission includes the negotiation of the management investment scheme and financial package (management package).

Throughout the period of the Buy-Out, Callisto keeps supporting its clients, in particular in the case of a large acquisition, and at exit, when the private equity fund sells its stake.

Thanks to its in-depth knowledge of the Private Equity market (investment funds, investment banks, financing banks, lawyers, auditors etc. ), Callisto is the investment bank of management teams.

Callisto is involved in a wide range of transactions (mid-caps and large-caps).
