Established in 2008, Kufner Group Plc operates as a holding company consolidating and managing its subsidiaries within its ownership portfolio through dedicated management areas and shared services that support all member companies of the Group.
Since 2022, Kufner Group has also provided freight transport and logistics services to all Group members through its Sirač branch.
Until recently, Kufner Group conducted its business through seven subsidiaries operating in three core areas: (1) mineral resources, (2) railway infrastructure, and (3) insulation materials.
In early July 2025, CRH, a global leader in building materials solutions, acquired Kufner Group’s mineral resources business segment, specifically the aggregates operations.
Operating four quarries in Eastern and Central Croatia, Kufner Group is the market leader in the Croatian aggregates industry.
The railway infrastructure and insulation materials segments, along with the affiliated companies Remont Pruga Matić d.o.o. and Kumal S d.o.o., were not part of the transaction and will continue their operations and further development independently, outside of Kufner Group.
The core activity of Kufner Group is the exploitation of mineral resources and the production of stone materials, i.e., aggregates of various types and grades, which are used across a wide range of industries including building materials production, construction, chemical industry, agriculture, and infrastructure projects. Stone aggregates, as fundamental building materials, are crucial components in many industrial processes, and are indispensable for road construction as well as the development and maintenance of railway infrastructure.
The mineral resources business area includes Kamen Sirač d.d., the cornerstone and leading producer with more than 140 years of tradition in the processing and refining of mineral resources as raw materials for numerous industries and construction, headquartered in Sirač near Daruvar. In addition to Kamen Sirač d.d., the mineral resources business area comprises Kamenolomi Banovina, organized through Kamenolom Međurače d.o.o. (part of Kufner Group since 2022, with significant reserves of mineral resources and its own deposit near Petrinja, as well as a gravel exploration site near Hrvatska Dubica); Kamenolom Bojna d.o.o. in Glina (acquired in 2024, strategically important for synergies in railway infrastructure and road construction projects); and Lika kamen d.o.o. (acquired in 2024).
Kufner Group aims to continue strengthening its leading market position in the key segment of mineral resource exploitation and aggregates production in Croatia, with plans for further expansion beyond the national borders, particularly by distributing its own products throughout the region. Continued organic growth will be supported by investments in modernizing current production capacities, business digitalization, research and development of new exploration sites, and securing long-term concessions.
We will also consider opportunities for further acquisitions within the core business segment of stone aggregates, both in Croatia and the broader region, in order to further consolidate our market position and ensure sustainable long-term growth.
The strategic locations of our quarries, together with the availability and quality of our stone materials, will provide Kufner Group with a strong position for the upcoming investment cycle in the railway infrastructure sector, thereby laying the foundation for continued stable growth and a sustained competitive advantage.
