SMABTP and MACSF seal their partnership by taking control of Arundo Re

The landscape of French reinsurance is undergoing a major transformation with the complete takeover of Arundo Re by a consortium formed by SMABTP and MACSF. This operation, completed in 2025, marks the full exit of the Caisse Centrale de Réassurance (CCR) and realizes a strategic partnership between two key players in the mutual and insurance sector. Arundo Re, now held at 70% by SMABTP and 30% by MACSF, establishes itself as a strengthened entity capable of better responding to the increasing challenges related to risk management, particularly in the construction sector and in the field of insurance innovation. This capital realignment illustrates a determined action aimed at consolidating the position of these mutuals in a rapidly evolving market where reinsurance plays a central role in securing all insurance contracts against multiplying hazards.

The acquisition dynamic is part of a tense environment both economically and regulatorily, where the ability to adapt and innovate constitutes a major challenge for insurance sector players. The complementarities between SMABTP, specialized in the construction sector, and MACSF, a leader in the healthcare professional market, offer Arundo Re renewed potential to develop customized, robust, and innovative reinsurance solutions. This capitalistic rapprochement marks a strategic turning point in the governance of the reinsurer, aimed at better risk control and increased commitment to mutualization for the benefit of its policyholders.

A strategic partnership between SMABTP and MACSF to strengthen Arundo Re in reinsurance

The partnership between SMABTP and MACSF, now the majority shareholders of Arundo Re, is part of a logic of consolidating the French reinsurance market. SMABTP, specialized in risk coverage related to the building and public works sector, and MACSF, a benchmark mutual insurance for health professionals, each benefit from specialized expertise in their respective fields. This partnership aims to pool these skills to improve risk management and optimize the reinsurance offerings provided by Arundo Re.

By taking control of 100% of the capital, both groups will be able to steer Arundo Re’s strategy toward targeted innovations, integrating regulatory evolutions and the increased demands posed by increasingly complex markets. These organizational and financial restructuring measures, combined with the technical expertise of both groups, should strengthen the solidity and competitiveness of the French reinsurer against major international companies.

• 🌟 SMABTP : Major player in the building and public works sector
• 🌟 MACSF : Leader in health insurance for professionals
• 🌟 Arundo Re : Second largest private reinsurer in France
• 🌟 Objective : Strengthen innovation capacity and risk management
• 🌟 Benefit : Reinforced mutual strategy, shared governance

Actor	Ownership share	Areas of expertise	Goals
SMABTP	70%	Construction insurance, risk management in buildings	Strategic strengthening, innovation, diversification
MACSF	30%	Health insurance, protection for professionals	Optimization of mutual offerings, digitalization
Arundo Re	100% (now)	Multi-sector reinsurance	Development, financial stability, innovation

It should be noted that this capital reorganization occurs at a time when the reinsurance sector faces increasing pressure both on financial markets and within the European regulatory framework, emphasizing the importance of agile and adaptable governance.

The implications of Arundo Re’s takeover on the French reinsurance market

The acquisition of all shares of Arundo Re marks a turning point in the organization of the reinsurance landscape in France. Indeed, this buyout by SMABTP and MACSF highlights several key issues:

• 🏢 The increased role of mutuals and mutual societies in a market traditionally dominated by public actors and private multinationals.
• ⚖️ The need for strategic adaptations in response to evolving regulatory requirements, such as Solvency II, and emerging risks (climatic, health, technological).
• 📈 A call for innovation and digitalization to improve risk assessment capabilities and internal process speed.
• 🌍 Strengthening financial sovereignty by avoiding excessive dependence on foreign reinsurers.

A fundamental element of this operation is risk diversification, thanks to the complementary expertise of SMABTP and MACSF. For example, the specific risks related to the building sector, especially exposed to natural disasters or cost overruns, are now better accounted for. Simultaneously, MACSF’s experience in health insurance provides a detailed understanding of risks in a sector subject to numerous regulatory changes and a strong human dimension.

Dimension	Before acquisition	After acquisition	Expected impact
Risk diversification	Less extensive, dependency on public markets	Extended to building and health sectors	Improved financial stability
Governance	Mixed, partial CCR participation	Fully mutual via SMABTP and MACSF	Enhanced decision-making agility
Innovation	More traditional processes	Integration of advanced risk management technologies	Increased responsiveness to disasters
Market position	Second private reinsurer in France	Strengthening as a strategic private actor	Enhanced resilience against international competitors

This repositioning is part of a long-term perspective where risk control and innovation capacity are already recognized as decisive differentiating factors within the insurance sector.

The specific challenges in risk management for the building sector with Arundo Re

The building sector, the historical core of SMABTP’s expertise, presents specific characteristics in insurance and risk management. Claims in this sector can involve significant financial issues, especially in the event of natural disasters, defects, or delivery delays. The integration of Arundo Re now allows for strengthened reinsurance capacities dedicated to these risks to better control potential impacts on insurance companies and policyholders.

The most pointed risks in this sector include:

• 🌪️ Amplified climate risks (floods, storms, frost)
• 🏗️ Construction defects and disputes
• 📉 Budget overruns and delays in projects
• 🚧 Management of ten-year guarantees and liabilities
• 📊 Complex assessment of multiple claims in case of catastrophe

Regarding these challenges, Arundo Re develops innovative solutions in collaboration with SMABTP:

• 📡 Use of connected sensors to monitor construction sites in real time
• 💻 Advanced risk modeling and analysis using artificial intelligence
• 🔄 Dynamic tariff adjustment based on risk indicators
• 🤝 Coordinated prevention programs with construction companies
• 🛡️ Establishment of dedicated funds to cover major claims

Building sector risks	Traditional approaches	Innovations introduced by Arundo Re	Benefits
Climate risks	Standard insurance with fixed premiums	IoT monitoring, integrated weather forecasts	Reduced claims and better reactivity
Defects / Disputes	Legal recourse via traditional methods	Preventive diagnosis via AI and regular audits	Lower litigation costs

This highlighting of advances in risk management builds a trajectory where Arundo Re strives to offer more effective protection while promoting responsible practices within the sector. This model will serve as an example for other insurance segments seeking to combine innovation and mutualization.

Concrete example: A successful crisis management on a construction site in Lyon

In 2024, a major construction project in Lyon was exposed to a series of extreme weather events. Thanks to intelligent monitoring deployed by Arundo Re and SMABTP, risks were anticipated and rapid intervention organized. The use of IoT sensors significantly limited losses, preventing budget overruns of several million euros. This decisive action directly protected the interests of insurers and involved companies.
