Prime Capital AG (“Prime Capital”) announces the final closing of its Prime Sustainable Infrastructure Debt Fund (“PSIDEF”) as of 31 July 2026. With the final close, the total volume of the strategy, including parallel and co-investment vehicles, amounts to EUR 305m.

PSIDEF was launched to address the financing needs of SME sponsors and independent infrastructure developers and asset owners across Continental Europe and the Nordics. These sponsors often have strong technical expertise, a local footprint and attractive asset pipelines, but limited access to tailored debt financing solutions. PSIDEF provides debt investments designed to support the construction, operation, and long-term ownership of sustainable infrastructure assets.

The strategy focuses on building a diversified infrastructure debt portfolio across attractive sub-sectors and jurisdictions. Since inception, PSIDEF has financed more than 70 assets structured across ten transactions. The portfolio includes investments in battery energy storage systems (“BESS”), energy efficiency and social infrastructure, among others. The broad diversification across assets, sectors, sponsors and geographies is a core element of the strategy.

PSIDEF targets a gross IRR of 9.5% to 10.5%, with a focus on regular distributions. The current portfolio generates a gross IRR of more than 10% and has been distributing a high cash yield since inception. The strategy seeks to provide investors with access to a stable portfolio of sustainable infrastructure debt investments, secured by real assets.

The fund is backed by eight institutional investors from Europe and East Asia, including insurance companies, pension funds, family offices and foundations. The investor base also includes the European Investment Fund, underlining the relevance of the strategy for financing sustainable infrastructure and supporting SME sponsors across Europe. The funds invested by PSIDEF benefit from support from the European Union under the InvestEU Fund.

Classified as an Article 9 fund under the EU Sustainable Finance Disclosure Regulation (“SFDR”), PSIDEF seeks to contribute to the decarbonisation of infrastructure, the promotion of energy efficiency and access to inclusive and modern infrastructure.

The most recent transaction was executed early September 2026 and comprises a highly diversified Energy-as-a-Service portfolio in Germany, including more than 40 underlying assets within a single transaction. The sponsor ElectroFleet operates a vertically integrated energy infrastructure platform, focused on providing decentralised energy solutions for large German offtakers. The company thereby combines on-site energy generation, BESS and EV charging infrastructure. The tailor-made financing supports a decentralised energy model under which electricity is generated and consumed at the same location, reducing reliance on the grid, enabling access to more cost-efficient energy and supporting the increased electrification of the offtaker’s vehicle fleet. The transaction has a tenor of c. 6.5 years and generates an expected IRR of c. 10%.

Commenting on the transaction, Mark Hellmann Regouby, CEO and founder of ElectroFleet, said: “The transition to electrified fleets requires significant upfront investment, operational flexibility and financing partners who understand both infrastructure assets and long-term decarbonisation needs. Prime Capital’s individual debt financing approach provides us with the capital and structuring flexibility required to scale these solutions efficiently, while allowing us to focus on delivering reliable, low-carbon energy infrastructure for our customers.”

“The transaction offers an attractive addition to our existing portfolio, by adding exposure to a new sub-segment in a strong jurisdiction, backed by an innovative sponsor with established assets and significant growth potential.”, adds Stefan Futschik, Head of Private Debt at Prime Capital. “We see this transaction as the starting point for a strong partnership with ElectroFleet and look forward to supporting the company’s growth over the coming years.”

PSIDEF continues to deploy capital into a diversified pipeline of sustainable infrastructure debt investments, including current opportunities across France, the Netherlands, Sweden and Spain. The pipeline reflects the strategy’s focus on assets with stable cash flows, strong collateral and tangible diversification benefits, including sectors such as energy efficiency, social infrastructure and sustainable transport infrastructure.

“We are very pleased to have successfully reached the final closing of PSIDEF, which marks an important milestone for our infrastructure debt platform,” said Andreas Kalusche, CEO of Prime Capital. “At the same time, we continue to raise capital for our asset-based strategies, which are designed to provide investors with differentiated sources of return and meaningful diversification across sectors, geographies and asset classes. The successful close of PSIDEF underlines the continued demand for tailored investment solutions that combine attractive risk-adjusted returns in the fixed income world with tangible exposure to real assets.”
