Rosendahl Nextrom, a manufacturing company that supplies production equipment to several industries, has signed an agreement to acquire TBS Engineering, a U.K.-based provider of battery assembly and plate manufacturing equipment, from Marmon Group.

Through its brand BM-Rosendahl, Rosendahl Nextrom provides manufacturing solutions for the battery industry. The company said acquiring TBS Engineering will expand its battery business and strengthen its position in battery manufacturing solutions.

“The acquisition of TBS marks a significant strategic step and underscores our clear commitment to the battery sector,” says Gerhard Jakopic, CEO of Rosendahl Nextrom. “It brings together two highly complementary companies with strong international relevance in their respective markets.”

The transaction follows Rosendahl Nextrom’s acquisition of Tallinn-based Windak Group in February of this year, which expanded its cable and wire division. After the TBS Engineering acquisition, Rosendahl Nextrom said its global workforce will exceed 1,000 employees.

The company said the transaction is the largest acquisition in its history. Financial terms were not disclosed.

“For our customers, this translates into greater technological depth, expanded global reach, and additional development opportunities,” says Siegfried Altmann, CEO of Rosendahl Nextrom. “We are building on our strong battery business and will continue to expand this area with a clear strategic focus.”

Based in Eastern Styria, Austria, Rosendahl Nextrom develops and supplies manufacturing equipment for the battery, cable and wire, and optical fiber industries. The company is part of the KNILL Group and, under its BM-Rosendahl brand, provides equipment and services for both lead-acid and lithium-ion battery production.

The company said TBS Engineering and BM-Rosendahl will continue to operate as independent brands with separate identities after the acquisition. Rosendahl Nextrom said it aims to build on the strengths of both businesses, combine their technical capabilities, and create additional opportunities in technology, service, and international market development.

According to Mercom’s Q1 2026 Funding and M&A for Energy Storage report, the corporate M&A activity increased, with seven companies acquired in the first quarter of 2026 compared to only one in Q1 2025.

In 2026, Nextpower, an integrated provider of utility-scale solar infrastructure solutions offering trackers, electrical balance-of-system solutions, software, and robotics, entered into a definitive agreement to acquire Prevalon Energy, a U.S.-headquartered joint venture between Mitsubishi Power Americas and EES, for total consideration of up to $365 million, excluding cash to be acquired.
