Founded in 1991, Rockfin is the worldwide #1 provider of complex auxiliary systems across all energy verticals generating global revenues of approximately €235 million in 2025. The company offers complex, end-to-end engineering solutions for the energy sector and Capmont believes it is well positioned to benefit from the continued global expansion of energy demand and the ongoing decarbonization trend.
The transaction was structured under Capmont’s control together with a consortium of blue-chip co-investors, including RIO Family Office, the investment vehicle of Rafal Brzoska. Capmont acquired Rockfin from Jet Investment, a Czech investment company. Rockfin’s three key managers will reinvest a significant portion of their proceeds and will actively support the company’s growth alongside Capmont. The transaction is subject to the approval of the relevant antitrust authorities.
The global energy market is characterized by strong long-term growth of around 15% annually, driven by rising energy demand and the transition towards cleaner energy sources. As a quality and technology leader, Rockfin plays a central role in this transformation, serving all major energy generation technologies, including compressors, turbines, renewable energy applications and hydrogen-related solutions. Capmont aims to strengthen Rockfin’s key position in the global energy market and support the further expansion of the company’s international footprint.
“Rockfin is an exceptionally well-positioned company, offering high-quality engineering solutions in a rapidly growing market”, said the deal leading partner of Capmont. “We see substantial potential to further expand the business, strengthen its international footprint and unlock additional value through operational excellence and additional efficiency gains. We plan to actively support OEMs in their development plans and to be a long-term, committed partner in advancing innovative solutions that enable the global energy transition.”
Rockfin employs more than 1,400 people worldwide, including over 600 engineers, and operates production sites in Poland and Saudi Arabia, as well as sales offices in the USA, Italy and Switzerland. The company covers the full value chain, from engineering and design to large-scale production of mission-critical systems for global energy infrastructure. “Capmont is an ideal partner for the next phase of Rockfin’s development. Their experience in scaling industrial businesses will support our international expansion, operational excellence initiatives, and continued investment in advanced engineering solutions across the energy value chain. We look forward to the cooperation and the continued development of the company”, said Michal Wróblewski, CEO of Rockfin.
Capmont was advised by Kearney and Arthur D. Little as commercial advisors, EY as financial advisor, and CMS as legal advisor. Jet Investment was supported by PwC Poland as financial advisor, Arthur D. Little as commercial advisor, and DLA Piper and DRV Legal as legal advisors.
