T2Y Capital Acquires Majority Stake in ACKERMANN to Boost High-Voltage Testing

T2Y Capital, a financial investor specializing in the energy transition sector, has completed a majority investment in ACKERMANN Anwendungstechnik & Vorrichtungsbau GmbH (ACKERMANN), a leading European provider of high-voltage testing systems. The deal, finalized in April 30, 2026 which includes a significant reinvestment by ACKERMANN’s existing management team, signaling strong confidence in the company’s future growth.

Headquartered in Weinstadt, Germany, ACKERMANN combines expertise in high-voltage engineering with advanced automation to deliver customized end-of-line testing solutions for cable component manufacturers and energy infrastructure original equipment manufacturers (OEMs). The company employs over 40 technicians and engineers who support blue-chip global clients, often expanding initial installations into long-term, multi-site partnerships.

ACKERMANN’s market position is reinforced by high switching costs and lengthy OEM re-qualification cycles, making its systems a critical, non-discretionary component embedded in production lines. Compliance with IEC standards mandates 100% end-of-line testing for every high-voltage cable component, underpinning steady demand for ACKERMANN’s solutions.

The acquisition aligns with T2Y Capital’s strategy to invest in market-leading companies positioned at key nodes of the energy transition value chain. T2Y’s portfolio already includes companies such as Wetrax, Prime Batteries, and Tretau, all relevant to high-voltage and grid infrastructure sectors.

Patrick Bettscheider, Co-Founder of 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.”

ACKERMANN’s management echoed this sentiment. “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 2018, the company’s two managing partners have transformed ACKERMANN from a niche operator into a European market leader in automated high-voltage end-of-line testing. The majority investment deal was signed and closed in April 2026.

The deal strengthens ACKERMANN’s position amid growing demand driven by the global rollout of renewables, grid expansion, and high-voltage direct current (HVDC) infrastructure projects. These trends are supported by multi-year government and utility commitments across Europe and beyond.

Looking ahead, T2Y Capital plans to leverage its industrial network and sector expertise to scale ACKERMANN’s multi-site OEM partnerships, enhance product offerings through advanced automation integration, and expand geographic reach. The partnership aims to maintain ACKERMANN’s technical excellence while accelerating growth in a structurally expanding market.
