Geneva, July 2nd, 2021 - 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 signed an agreement to create the leading independent European insurance broker operating worldwide. A consortium of institutional investors, led by Ontario Teachers’ Pension Plan Board (“Ontario Teachers”) and including Bpifrance 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 newly formed Group will hold the majority of the 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.
In Switzerland, this operation initiates the merger of Swiss Risk & Care and Qualibroker, these two companies being respectively subsidiaries of SIACI SAINT HONORE and GROUPE BURRUS COURTAGE.
The merger of SIACI SAINT HONORÉ and BURRUS GROUP will create a significant independent European alternative to the major global brokers.
The combined Group will strengthen its market position in Switzerland, in France, in Europe and around the world in the large company, public entities, mid-cap and SME market segments, in insurance, pension and HR services.
The combined Group will be among the top 10 global players in the sector with a turnover of almost €700 million and close to 5,000 employees in over 40 countries.
As part of this transaction, Charterhouse Capital Partners, which acquired a majority stake in SIACI SAINT HONORÉ’s in 2018, will exit the business, following a period of significant organic and acquisitive growth under its ownership. Ontario Teachers’ Pension Plan will acquire a 30% stake and become the largest institutional shareholder in the newly formed Group, with Bpifrance (10%) and Cathay Capital (5%), alongside other institutions like Ardian, comprising the remaining shareholders.

The transaction is expected to close in the second half of 2021, subject to customary regulatory and anti-trust filings.
