BU Bregal Unternehmerkapital Acquires Majority Stake in A.Eberle

Funds advised by BU Bregal Unternehmerkapital (BU) have agreed to acquire a majority stake in A.Eberle GmbH & Co. KG, a specialist in measurement, control, and regulation technology for electrical energy infrastructure. The transaction, announced on April 14, 2026, is expected to close by the end of the second quarter, subject to customary regulatory approvals.

A.Eberle, founded in 1980 and headquartered in Nuremberg, Germany, develops hardware and software solutions that monitor, control, and optimize grid quality. Its product portfolio includes voltage regulation, earth fault regulation and compensation, and power quality monitoring systems. These solutions support grid stability and the integration of renewable energy sources, serving primarily transmission and distribution system operators (TSOs/DSOs) and medium to large industrial customers across Europe.

BU, a leading mid-cap investment firm based in Zug, Switzerland, manages over €7 billion in assets and focuses on partnering with mid-sized companies in the DACH region and neighboring markets. The firm aims to support A.Eberle’s international growth, enhance product development, and strengthen its position as a technological leader in grid stability and power quality.

The management team of A.Eberle will reinvest alongside BU, maintaining a significant role in driving the company’s long-term growth strategy. Lothar Mayer, majority owner of A.Eberle, highlighted the shared entrepreneurial values and trust between the parties, expressing confidence in BU’s ability to guide the company through its next growth phase. Stefan Hoppert, CEO of A.Eberle, emphasized the partnership’s potential to advance technological development and scale solutions to meet modern power grid challenges.

Felix Werdin, Partner at BU, noted that A.Eberle is well positioned in a structurally growing market driven by the expansion and digitalization of power grids, increasing renewable energy integration, and rising electricity demand fueled by electromobility and data centers. He underscored the significant potential for growth and innovation in collaboration with A.Eberle’s experienced management team.

The deal terms remain undisclosed. However, the partnership is expected to leverage BU’s capital and network to accelerate A.Eberle’s international market expansion, optimize research and development efforts, and enhance go-to-market strategies. The collaboration aims to expand A.Eberle’s product portfolio to address emerging grid digitalization needs and strengthen customer-specific solution customization.

The energy infrastructure sector is undergoing rapid transformation, with increasing demand for stable, efficient, and digitally managed power grids. A.Eberle’s expertise in power quality and grid stability positions it to capitalize on these trends. The partnership with BU is anticipated to intensify competition in the European market, prompting rivals to boost innovation and expand their offerings.

Looking ahead, the integration will focus on aligning management and ownership interests, maintaining innovation momentum, and navigating regulatory environments in new markets. Both parties aim to preserve the high quality of customer-specific solutions while scaling operations internationally.

This strategic investment marks a significant step for A.Eberle as it seeks to consolidate its leadership in grid technology and expand its global footprint with BU’s support.
