Jet Investment completes sale of energy giant Rockfin to German Capmont group and its partners
After approval by all the relevant regulatory authorities, the sale of the Polish energy company Rockfin has been successfully completed. Jet Investment announced the transaction on 17 December and has now formally closed the process. The new owner is a consortium consisting of Capmont and its partners. The deal is one of the most significant divestments made by a Czech investor last year. Rockfin was the most profitable project in the portfolio of funds managed by the Jet Investment group at the time of the exit.

Jet Investment acquired a 100% stake in Rockfin in 2022 through the Jet 2 fund. “We purchased our interest in Rockfin with the clear goal of building a global player in support systems for the energy industry. We have not only managed to achieve this goal, but have exceeded it in many areas,” said Jiří Kroc, Jet Investment’s project director.
In less than four years, the Jet Investment group tripled its revenue growth. It increased from CZK 2 billion to CZK 5.8 billion (EUR 235 million). In addition to significant growth in business volume, the company’s international presence was also strengthened and its customer portfolio expanded. “We achieved these results despite Rockfin entering our portfolio in an extraordinarily complicated situation following the launch of the Russian invasion of Ukraine. Nevertheless, we successfully guided the company through this challenging period and started its systematic transformation,” said Kroc.
These steps directly translated into further growth in orders and development of Rockfin’s core competencies. “In the past year alone, we launched our own hydrogen technologies through which Rockfin is now building several large hydrogen refuelling stations in Poland. As a result, it acts as a complete solution provider in the role of OEM supplier,” explained Kroc.
The creation of the Defence division, focused on hydraulic systems for the defence industry, was also an important element of the company’s further development. “We were able to move this division forward both in terms of personnel and production capacity,” added Kroc.
Today, Rockfin employs more than 1,400 people and operates production facilities and branches in Poland, the USA, Italy and Switzerland. Under the leadership of Jet Investment, the company expanded its international presence through partnerships in markets such as Turkey, China and South Korea, and also successfully established itself in Saudi Arabia. Rockfin has thus become one of the global leaders in its specialised segment and is one of the key suppliers of energy infrastructure worldwide.
“Following the sale of the energy and engineering group Tedom, which was one of the largest transactions on the Czech market, Rockfin is continuing its series of successful exits by the fund executed after achievement of the investment objectives and the approaching end of its investment horizon. The repeated exits confirm our ability to create value in the long term and realize it at different stages of the investment cycle,” said Marek Malík, managing partner at Jet Investment.
A consortium of investors led by the Capmont group became the new owner of Rockfin. The sale took place with the participation of the Polish investment company RIO Asi, co-founded by the businessman Rafał Brzoska. The transaction was successfully completed after approval by all the relevant regulatory authorities. The consortium plans to build on Rockfin’s current strategy of growth and geographic expansion under Jet Investment, focusing in particular on further development of operations in the United States and gradually in other regions, especially Asia.
The Jet Investment group was supported by leading advisory firms in the transaction. The lead sell-side advisor was PwC’s Polish office, the commercial advisor Arthur D. Little and legal advisors DLA Piper and DRV Legal.
The Jet 2 fund’s portfolio continues to include 2JCP (CZ), an energy specialist, and the printing group EDS (DE). Jet Investment is currently investing in the Jet 3 private equity fund and plans to gradually raise capital from private and institutional investors in the newly opened Jet 4 fund to acquire industrial enterprises.
