Le groupe Siaci Saint Honoré et le groupe Burrus annoncent leur intention de créer un leader européen indépendant du courtage et des services-conseils en assurance

Ontario Teachers’ Pension Plan Board will lead the investor consortium and acquire a 30% stake in the combined group, becoming the largest institutional shareholder. Bpifrance and Cathay Capital will acquire a 10% and 5% stake respectively

Paris - The management of the SIACI SAINT HONORÉ Group, the leading independent French insurance broker, and Christian Burrus, the majority shareholder of DIOT and LSN, have entered into exclusive negotiations with a view to jointly creating the leading independent European insurance broker operating worldwide. A consortium of institutional investors, led by Ontario Teachers’ Pension Plan Board (“Ontario Teachers”) and including BPI and Cathay Capital, will become significant shareholders in the Group.

With this transaction, the BURRUS GROUP, headed by Christian Burrus, together with the management of the combined Group will hold the majority of the [outstanding share] capital and voting rights in the Group, guaranteeing its independence and sustainability. Pierre Donnersberg will become chairman of the group and Christian Burrus Managing Director.

The merger of these two groups will create a significant independent European alternative to the major global brokers.

The combined Group will strengthen its market position in France and around the world in the large company, mid-cap and SME market, in personal insurance, property and liability insurance, credit insurance and reinsurance. It will be among the top 10 international players in the sector with turnover of almost €700 million and close to 5,000 employees in over 40 countries.

As part of this transaction, Charterhouse Capital Partners, SIACI SAINT HONORÉ’s majority shareholder since 2018, will sell its majority stake. Equity financing will be provided by leading international investors, reflecting the international ambitions of the Group. Ontario Teachers’ will acquire a 30% stake and become the largest financial shareholder in the Group, while Banque Publique d'Investissement (BPI) will acquire a 9.6% stake and the Franco-Chinese Cathay Capital a 5% stake.

A pool of banks (made up of Deutsche Bank, Nomura and Société Générale as physical book-runners, with the support of CA-CIB, Citi and Natixis) has underwritten the debt financing for the transaction. The transaction is expected to be finalized in the second half of 2021.

Pierre Donnersberg said, “We share common values and a wealth of opportunities. This merger will generate new opportunities and the implementation of ambitious growth plans built on large business synergies.”

Christian Burrus confirmed, “The family shareholding values that drive me remain at the heart of this project: they preserve our independence and guarantee it in the long term in the interest of our teams, our clients and our investors.”

Nick Jansa, Senior Managing Director, Europe, the Middle East and Africa, for Ontario Teachers’ said: “We are pleased to be partnering with Pierre Donnersberg, Christian Burrus and the combined management team to help them to create an independent European leader in insurance brokerage.
