H.I.G. Capital (“H.I.G.”), a leading global alternative investment firm with USD 75 billion of capital under management, recently announced that one of its affiliates has entered into a definitive agreement to acquire a majority stake in TERRAS Group. TERRAS’s co-founders, Dr. Dirk Sojka and Ralf Sojka, will reinvest alongside H.I.G., affirming their commitment to the Company’s continued growth trajectory.
Headquartered in Montabaur, Germany, TERRAS is a leading provider of infrastructure engineering and construction services across the mobility, energy, digital, water, and urban development sectors in the DACH region. The Company delivers comprehensive civil infrastructure solutions spanning regional infrastructure, specialty foundation engineering, rail construction, and related engineering services.
Supported by Germany’s significant infrastructure investment needs, an accelerating energy transition, and growing demand for digital infrastructure, TERRAS is well positioned for continued growth. H.I.G. plans to support the Company’s next phase of expansion by increasing cluster density within its existing German markets while selectively expanding into new geographies.

Rohin Jain, Managing Director at H.I.G. Middle Market Europe, commented, “TERRAS exemplifies the type of business we look to partner with – a founder-led platform with a proven formula operating in a large, structurally attractive market. Germany’s decades-long infrastructure investment backlog, coupled with the accelerating energy transition, provides an exceptional long-term growth opportunity for the Company. We are proud to be their partner for the next chapter, and we look forward to supporting the team as it scales TERRAS into a business of true national and European significance.”
Dr. Dirk Sojka and Ralf Sojka, co-founders of TERRAS, added, “When we founded TERRAS, we had a clear vision to build a platform capable of delivering the full civil infrastructure value chain while preserving the entrepreneurial culture that makes regional specialists so successful. Today, that vision is becoming a reality, and we believe we are only at the beginning of our journey. H.I.G. has a deep understanding of our business and a proven track record of partnering with founder-led companies to support our next phase of growth.”
