Graz – [March 20th,2025] – Christof Group, a leading provider of high-pressure equipment solutions and industrial services, is pleased to announce the acquisition of 85 % of the share capital in ATB Riva Calzoni Oil and Gas Division, a renowned manufacturer and part of ATB Group, that is specialized in high-pressure technology. The remaining 15 % in the company will be transferred to Christof Group after a transition period of three years. This strategic acquisition strengthens Christof Group's position as a key player in the high-pressure equipment manufacturing industry and expands its portfolio to include innovative technologies and specialized products. The company will operate in the future as Marghera Oil & Gas S.r.l.

The acquisition of Marghera Oil & Gas S.r.l enhances Christof Group’s capabilities to deliver cutting-edge high-pressure equipment to a broader range of industries, including large apparatus and reactors with a weight of more than 1000 tons. The integration of ATB Oil & Gas’s advanced engineering, R&D expertise and robust product line in the Oil & Gas sector as well as in the Ammonia market will complement and expand Christof Group’s existing offerings, enabling the group to better serve both new and existing customers. Especially in the ammonia sector, that is seen as an energy source for the energy transition, Christof Group sees a huge potential for the future.

 

“Christof Group has taken an important step into the future,” said Stefan Christof, CEO of Christof Group. “This acquisition aligns with our strategic vision to expand our product portfolio, strengthen our market presence and continue to offer world-class high-pressure and industrial solutions to our customers. The synergies between our two organizations will drive innovation and position us for continued growth in a rapidly evolving market.” This investment will also provide Christof Group with enhanced operational efficiencies thanks to the well-equipped production site in Port Marghera, increasing production capacity, respectively offering the great advantage of direct transport of the large and heavy equipment via the sea.
The deal was finalized on 13th March 2025. Christof Group plans to integrate ATB Oil & Gas’ operations seamlessly into its existing structure, ensuring continuity of service and quality.
