S&B Strategy advises FASTR on the acquisition of Velero Energy Services GmbH and Contherma GmbH from the Velero Group
Our team provided comprehensive advice to FASTR GmbH (FASTR) on its acquisition of Velero Energy Services GmbH (VES) and Contherma GmbH (Contherma), both of which are part of the Velero Group.
FASTR, formerly EGC Energie- und Gebäudetechnik-Control, is a leading energy service provider headquartered in Düsseldorf. With this transaction, the company is consistently pursuing its growth strategy and expanding its position as a decarbonisation partner for the real estate industry. In February 2025, the company entered into a strategic partnership with KKR. FASTR manages a real estate portfolio of over two million square meters for more than 260 clients and operates approximately 1,100 central heating plants as well as about 75 district heating networks with more than 3,000 meters. Its range of services covers the entire value chain—from the planning and design of energy and building systems through financing, operation, and maintenance to energy supply.
VES and Contherma, two companies specialising in heat contracting, were acquired by Velero, a real estate company operating nationwide, as part of a share deal. Velero is an established repositioning specialist focused on the acquisition and management of residential real estate in Germany, particularly in the affordable housing segment. The company currently manages approximately 24,000 residential units in about 150 cities, with a geographic focus on economically strong B and C cities throughout Germany. The heating portfolio managed by VES and Contherma comprises a total of approximately 6,000 residential units.
S&B Strategy served as FASTR’s lead M&A advisor throughout the entire acquisition process until the successful signing and also supported FASTR in conducting commercial due diligence.
