EN: Arcus Infrastructure Partners acquires majority stake in the Einhundert group of companies

Cologne/London, 15th January 2024: Leading European infrastructure fund manager, Arcus Infrastructure Partners (“Arcus”) has acquired a majority stake in the EINHUNDERT group of companies. The acquisition was made through Arcus European Infrastructure Fund 3 and its portfolio company Officium GmbH (“Officium”).

EINHUNDERT, which comprises EINHUNDERT Energie GmbH and its solar PV financing companies, is a market leader in multi-tenant solar electrification. Through its acquisition, Arcus will drive the ambitious growth agenda for the company, including the financing of more than 100 MW of rooftop solar PV systems in the coming years.

Senior Investment Director at Arcus, Christian Scott-Mackenzie commented, “We believe that EINHUNDERT offers a highly attractive solution to decarbonise multi-dwelling properties, providing cheap and clean power generated on site. We are convinced that the strong fit with the Officium platform will provide mutual benefits to both companies and we look forward to supporting the EINHUNDERT team on its next phase of growth.”

Founder, Dr. Ernesto Garnier will remain as co-investor and continues to serve as CEO. “We are delighted to welcome Arcus as our new majority investor and strategic partner. I look forward to serving the German real estate market in close cooperation with the expert team at Arcus. The energy transition in the multi-tenant building sector requires scalable solutions and massive capital investments. Together, we can provide exactly that.”

The partnership between Officium and EINHUNDERT will enable a bundled product offering to multi-tenant building owners, decarbonising their power and heating needs with a clean, economic, simple and long-term solution that sits behind the meter.

“Real estate companies need seamlessly integrated services across solar electrification, metering and energy management. Through the partnership between Arcus, Officium and EINHUNDERT, we will be the first to actually meet this demand,” says Dr. Ernesto Garnier.
Officium’s CEO, Stephan Kiermeyer adds: “Together with Einhundert, we offer the housing industry the complete process and value chain for energy requirements: solar PV, tenant electricity and metering. This is unique on the German market. We are thus further expanding our areas of expertise and are the ideal partner in the field of metering and energy services.”

This transaction marks a successful exit for all venture capital and angel investors who have financed EINHUNDERT to date, including Triodos Energy Transition Europe Fund, EWE, NRW.Bank, Übermorgen Ventures, and kopa ventures (formerly WiVenture).

EINHUNDERT, Arcus, and Officium are excited to work hand in hand with customers to decarbonise their building stock and provide the highest quality, integrated product offering in the German market.
