Mount Street supports successful second closing of Helaba infrastructure debt fund
Second closing reflects continued institutional demand for infrastructure debt and supports the further growth of Helaba’s HLB Private Markets platform.
Mount Street has supported Helaba Landesbank Hessen-Thüringen (“Helaba”) in completing the successful second closing of its Infrastructure Debt Fund I, part of the bank’s HLB Private Markets platform.
Launched in 2023, HLB Private Markets provides institutional investors with exposure to senior infrastructure loans originated by Helaba. The second closing includes the participation of a leading international institutional investor and builds on the fund’s initial closing in 2023.
Mount Street has acted as independent portfolio manager to Infrastructure Debt Fund I since launch, overseeing investment selection, portfolio monitoring and governance, as well as supporting the fund’s fundraising strategy and the continued development of the wider HLB Private Markets platform.
The fund provides exposure to infrastructure assets across digital infrastructure, renewable energy and transportation. While the majority of projects within the current portfolio are based in Germany, alongside projects spanning Ireland, wider Europe and the Netherlands.
The second closing comes as Helaba reports strong demand and a healthy pipeline for further infrastructure assets, while the platform is also working towards the launch of additional debt funds and separately managed account mandates for investors.
Erwin Hennenberg, Managing Director at Mount Street, commented: “The successful second closing highlights the growing demand from institutional investors for high-quality infrastructure debt investments supported by strong origination capabilities and independent portfolio oversight. We are proud to continue supporting HLB Private Markets as independent portfolio manager and strategic partner as the platform continues its growth trajectory.”
Ingo Wichelhaus, Co-Head of Business Development at Mount Street, added: “The second closing is a significant achievement that demonstrates the scalability of the HLB Private Markets platform. Since inception, Mount Street has supported the platform across structuring, fundraising and portfolio management activities. We are delighted to continue working alongside Helaba while supporting the platform’s future expansion into additional debt strategies.”
The second closing forms part of Helaba’s longer-term strategy to grow HLB Private Markets, with further debt fund strategies and institutional mandates under development. The fund is currently targeting a total volume of approximately €500 million.
