What we do

In recent years, the importance of private equity (PE) as an asset class has rapidly increased and deal activity has surged to record levels. Still it is understudied academically and success factors of PE investments are not yet fully understood. The Center for Corporate Transactions and Private Equity (CCTPE) is a think tank for private equity buyouts that aims at closing this gap. The purpose of the Center is to foster high quality research output, and provide a platform for renowned scholars and industry professionals at HHL Leipzig Graduate School of Management – one of the leading business schools in Europe. Over the past years, a team of renowned and experienced scholars has created a competitive database on PE buyouts and received considerable media attention as well as several scientific awards for its research. Several high-profile companies and individuals are partnering with us to further expand our database and research. We gratefully acknowledge support by AssetMetrix, Astorius, The Boston Consulting Group, Börsen-Zeitung (as part of WM Gruppe), CatCap, as well as a HHL alumnus.

Robert Loos
Private Equity Investment Professional at EQT , Alumnus Doctoral Program

As an alumnus of HHL’s Chair of Financial Management, I am proud and happy to see the successful launch of the Center for Corporate Transactions and Private Equity. After having myself moved from academia back to business as a private equity investment professional, I strongly second CCPTE’s focus on high quality research while maintaining close ties to the practical world of investing and deal making at the same time.

As a doctoral candidate at the Center for Corporate Transactions and Private Equity I was able to work on the forefront of academic research on private equity and develop knowledge relevant for both academia and practice
