From in-house foundation to trusted reinsurance partner

Who We Are
Stonefort Reinsurance is a Luxembourg-based, A-rated reinsurer built to deliver long-term value.
 
Originally created to serve the risk needs of HOCHTIEF and ACS — global leaders in construction — we’ve evolved into a focused reinsurance partner for clients across Europe and beyond.
 
Our strength lies in our underwriting discipline, operational mindset, and ability to support complex risks with clarity and consistency.
Our Difference
Stonefort Reinsurance is the core risk platform of HOCHTIEF and ACS Group.
 
Originally established to serve the insurance needs of our shareholder’s international operations, we have grown into a fully licensed Luxembourg-based reinsurer with a strong technical and financial foundation. In 2018, we expanded our business model to also serve external clients throughout Europe.
 
Our focus lies in providing treaty reinsurance solutions with specific expertisefor complex risks across the construction and infrastructure sectors. We support group entities and third-party partners by offering long-term capacity, underwriting discipline, and close cooperation.
 
We have built a strong foundation in European-based portfolios, leveraging our deep understanding of local market dynamics. We offer capacity and support for the unique needs of the European reinsurance landscape.
 
APAC represents a major growth opportunity for our business. With the appointment of a highly experienced advisor and former regional leader in the APAC region, we are laying the groundwork for a strong and committed presence across Asia-Pacific.
We don’t follow market cycles — we help our clients
navigate them.
We build
long-term capacity, not opportunistic deals.
We speak the language of risk, and we bring reliable solutions.
