REHLKO EXPANDS DATA CENTER BACK-UP POWER OFFERING WITH ACQUISITION OF THE WILMOTT GROUP

Acquisition Strengthens Position in Data Centers & Mission-Critical Segments

MILWAUKEE, Wis., July 10, 2025 /PRNewswire/ -- Rehlko, a global leader in energy resilience, announced today it has reached a tentative agreement to acquire The Wilmott Group, a premier supplier of critical back-up power solutions in the United Kingdom. This acquisition establishes Rehlko as one of the leading energy resilience providers in the U.K. and strengthens the company's position as a global leader in delivering energy solutions critical to sustaining and improving life. The Wilmott Group will operate as part of Rehlko's Europe, Middle East, and Africa (EMEA) business – a global leader in backup power solutions for the most critical applications.

The Wilmott Group's comprehensive capabilities in design, testing, installation and service will strengthen and support the acceleration of Rehlko's core and aftermarket service offerings. This acquisition will also deliver manufacturing and engineering efficiencies to support the strategic expansion of Rehlko's data center position across EMEA.

"The Wilmott Group's dedication to creating long-term value with customers strongly complements Rehlko's commitment to delivering innovative and reliable energy solutions," said Brian Melka, President and Chief Executive Officer of Rehlko. "In this new chapter for Rehlko, The Wilmott Group's long history of success will bolster our data center solutions across the U.K. and the rest of Europe."

The Willmott Group includes critical power specialist WB Power Services (WBPS) as well as power and industrial acoustic product manufacturer, Wiltech Acoustics.

Backed by Rehlko's expansive organization, WBPS' project engineering team will enhance collaboration across data center projects—a key focus of this partnership—while strengthening Rehlko's position in the data center space across EMEA. Rehlko will also leverage Wiltech's in-house enclosure manufacturing capabilities to reduce production time and enable greater flexibility in meeting customer needs and market demand.

Rehlko was acquired by Platinum Equity in 2024. Since its establishment as an independent company, Rehlko has continued to provide control, resilience and innovation through a comprehensive range of energy solutions. The Wilmott Group's 19 locations across the U.K. and support at more than 4,000 critical power plants adeptly enhances Rehlko's positioning as a reliable partner to data centers and other commercial operations across EMEA.

"The addition of WBPS expands Rehlko's data center capabilities and service offerings across EMEA, enhances vertical integration in enclosure manufacturing, and strengthens relationships with key European customers," said Platinum Equity Co-President Jacob Kotzubei and Managing Director Matthew Louie in a joint statement. "The acquisition also represents another significant milestone in our commitment to investing in Rehlko's growth, both organically and through strategic acquisitions. We look forward to partnering with the company to pursue additional opportunities to grow the business across its verticals."

Andy Wilmott, Co-CEO and Chairman of Wilmott Group, shared "We're thrilled to be joining forces with the Rehlko team. Combining our shared capabilities will enable us to continue delivering reliable, trusted back-up power solutions to data centers, hospitals, schools, and other critical infrastructure across the United Kingdom, Europe, the Middle East and Africa. Together, we also will realize operational improvements and organizational efficiencies."
