- ACKERMANN's bespoke high-voltage testing solutions are mission-critical, non-discretionary infrastructure embedded in blue-chip OEM production lines
- The majority investment marks T2Y Capital's fourth platform investment from its inaugural fund
- Management of ACKERMANN reinvests a significant stake alongside T2Y Capital
Munich & Weinstadt – 30 April 2026 – T2Y Capital, a financial investor focused on the energy transition, today announced its majority investment in ACKERMANN Anwendungstechnik & Vorrichtungsbau GmbH (ACKERMANN), a European leader in high-voltage testing systems. The company’s existing management team will reinvest a significant stake alongside T2Y Capital, underscoring their conviction in ACKERMANN's growth trajectory.
Headquartered in Weinstadt (Germany), the testing specialist and system integrator combines deep high-voltage expertise with advanced automation know-how. Its team of more than 40 technicians and engineers serves blue-chip global cable component and energy infrastructure OEMs, with a consistent pattern of expanding from initial installations to long-term, multi-site partnerships.
Long OEM re-qualification cycles and high switching costs make ACKERMANN’s competitive position highly durable. With IEC standards mandating 100% end-of-line testing for every high-voltage cable component, its systems are a non-discretionary spend item deeply embedded in OEM production lines.
The demand for ACKERMANN's systems is structurally underpinned by the global rollout of renewables, grid expansion, and HVDC infrastructure, backed by multi-year government and utility commitments across Europe and beyond.
This makes ACKERMANN a natural fit for T2Y Capital’s focus on market-leading companies at critical nodes of the energy transition value chain and its portfolio of high-voltage and grid-infrastructure relevant companies, including Wetrax, Prime Batteries and Tretau.
T2Y Capital will help ACKERMANN scale operations, accelerating its profitable growth.
Deborah Grömling, Managing Director at T2Y Capital, commented:
“Europe’s grid infrastructure is being rebuilt at an unprecedented pace, and every component requires rigorous end-of-line testing. ACKERMANN is the go-to partner for OEMs. We are excited to partner with their team to unlock the company’s potential. By providing our deep sector expertise and industrial network, we will support their next phase of growth.”
The two Managing Partners and owners of ACKERMANN, commented:
“We have built ACKERMANN into a trusted partner for energy infrastructure OEMs across Europe. In T2Y Capital, we found an investor who shares our entrepreneurial values and brings a deep understanding of our market. Together, we will capture the accelerating demand from grid expansion and HVDC build-out while maintaining the technical excellence and customer focus that define ACKERMANN.”
Since acquiring ACKERMANN in 2018, the two Managing Partners have built the company from a specialized niche operator into a European market leader in automated high-voltage end-of-line testing.
The majority investment in ACKERMANN was signed and closed in April 2026. T2Y Capital was advised by EY Parthenon (Commercial & Financial), KPMG (Tax & Structuring), SNP (Legal), ERM (ESG), Marsh (Insurance), yami advisory (Debt Advisory) and Astera (Financing Legal).
The Shareholders of ACKERMANN were advised by Commerzbank (M&A), Luther Rechtsanwaltsgesellschaft (Legal), RSM Ebner Stolz (Financial & Commercial) and HWS (Tax). The acquisition financing is provided by NORD/LB.
