Jet Investment sells energy giant Rockfin to Capmont and its partners

The share purchase agreement (SPA) was signed on 17 December 2025, but the transaction is subject to approval by the relevant regulatory authorities. Thus, the settlement of the deal is expected by the end of January 2026. The parties involved agreed not to disclose the details of the transaction, including its value. A minority stake will remain with the company's three key managers, reinvesting a large part of the funds obtained from the sale and staying in the company’s management.

The sale of Rockfin is the second major exit for Jet Investment in the recent year. The first was the sale of TEDOM, an energy and engineering group, to Yanmar Group in October 2024.

"We were successful in establishing the company as a world market leader in the field. Over the four years of our presence, we tripled the sales. We are selling the company in excellent condition – 2025 was a record year in all respects, Rockfin's order book reaches the highest value in the company's history, and the trend of rapid growth will continue in the coming year," says Jiří Kroc, Project Director at Jet Investment, adding: "The strong investor interest during the sale process confirmed Rockfin's position as a key supplier and a global leader in its field."

Rockfin is one of the world's leading Tier 1 suppliers of critical systems for energy infrastructure, specializing in complex systems for the energy sector, including compressors, turbines, generators and renewable energy. With more than 1,400 members of staff, including 600 highly skilled engineers, and production plants and branches in Poland, the USA, Italy, Switzerland and Saudi Arabia, the company will achieve record sales of around CZK 5.8 billion / EUR 235 million. Rockfin is currently the most profitable project in the portfolio of funds managed by Jet Investment.

"Our investment goals have been met and with regard to the approaching end of the fund's investment horizon, we are gradually selling the companies from the portfolio," explains Marek Malík, Managing Partner of Jet Investment. "After the successful sale of TEDOM to Yanmar Group in October 2024, Rockfin was logically the next step. This sale confirms that our active investment approach and strategy of the Jet 2 fund with a focus on Central European industry and energy are working. Two such successful exits in one year also demonstrate Jet Investment's ability to implement successful exits in the long term and to continuously return capital to investors," adds Marek Malík.

The Capmont consortium plans to continue on the company’s set growth course and keep up the geographical expansion launched under Jet Investment’s leadership. The focus is on new markets in the USA while also considering other regions, especially in Asia. In addition, the company is planning to expand Rockfin's business scope with its own product lines and also in the field of services.

"In the recent years, Rockfin has undergone a transformation from a successful local company to a key global player in the energy sector. With the new owner at our back, we will continue to strengthen our position. We look forward to the cooperation and further development of the company," says Michal Wróblewski, CEO of Rockfin.

During the transaction, Jet Investment was supported by leading advisory firms. PwC Poland was a lead sell-side advisor, commercial advisory was rendered by Arthur D. Little, and DLA Piper and DRV Legal assumed the role of legal advisors. Capmont consortium was advised by commercial advisors Kearney and Arthur D. Little, EY acted as the financial and tax advisor and CMS as the legal advisor.

The portfolio of Jet 2 still includes 2JCP (CZ), a company specializing in the energy sector, and EDS (DE) printing group. Currently, Jet Investment completes investments under the Jet 3 private equity fund and launches Jet 4 to gradually raise up to EUR 350 million from private and institutional investors and acquire industrial companies.
