Diot-Siaci Group, an independent insurance and reinsurance brokerage, announced total revenue of 1.31 billion euros for the year ending December 31, 2025.
Results were up 28% on the prior year, driven by organic growth of 5.5% (excluding the impact of foreign exchange) and targeted acquisitions.
This positive performance is due to the Group’s ongoing Horizon 2029 strategic plan, the results of which confirm the relevance of the business model and the roadmap deployed by Group CEO Cédric Charpentier.
In 2025, the group’s capital structure will undergo major changes. In November 2025, the Diot-Siaci Group finalized a new ownership structure, with long-term shareholder Burrus Group increasing its shareholding from 42% to 47%.
In September 2025, private investment company Ardian became the main financial shareholder, holding 45% of the shares. Management and employees hold 8% ownership.
The new capital structure includes joint controlled governance between Ardian and Burrus Group to support future growth. Cathay Capital sold a minority stake of approximately 5% held since the 2021 merger of Diot-LSN and Siaci Saint Honoré.
Diot-Siaci is also doing well in its domestic market outside of France. Revenues in Europe and the Rest of the World continued to grow to €610 million, compared with €454 million in 2024 (+34%), in line with the Group’s international strategy, benefiting in particular from the rapid growth in the Middle East and Africa. Revenue in France increased by 21% to €698 million, compared with €576 million in 2024.
Diot-Siaci Corporate Solutions, one of the Group’s business units and the entity primarily dedicated to property and casualty (P&C) activities in France for large accounts and the middle market, reported total revenues of €287 million, up more than 5% from €274 million in 2024, supported by strong commercial momentum in most business lines, especially in the middle market segment.
Total revenue of Diot-Siaci’s French and International Staff Benefits segment (PSFi) increased by almost 4% in 2025 to approximately €166 million. This is an increase from nearly €160 million in the previous year (based on like-for-like comparison, excluding HR consulting activities).
Following the acquisition of the Oasys & Cie Group, HR Consulting is now an independent business unit within the Group, with reported revenues of €137 million.
MSH, a subsidiary dedicated to providing employee benefits to globally mobile individuals, posted revenues of €142 million in 2025, compared with €136 million in 2024 (net of foreign exchange effects, +5% and 8% respectively).
The Diot-Siaci Credit entity’s credit insurance, bond and financing activities generated revenue of €51 million.
Finally, the “International” business unit, which brings together specialized businesses such as transport and marine insurance, captive management, and reinsurance, as well as operations in the EMEA region (Europe excluding France, the Middle East and Africa) and the rest of the world (Singapore), generated revenue of 525 million euros, up 42% from 369 million euros in 2024.
Diot-Siaci noted that this growth reflected the impact of the merger with the Nasco Group and acquisitions completed in Africa.
