Carlyle inks rumoured US$3.5Bn sale of drive systems supplier Flender 

Carlyle has agreed to sell Germany-based mechanical drive technology business Flender to the Triton Partners equity-backed Triton Fund 6.

The terms of the transaction were not disclosed, but Bloomberg cited sources familiar with the deal estimating its preliminary value at US$3.5Bn. Carlyle said the transaction is expected to close in Q4 2026.

Triton Fund 6 closed in mid-March 2026 with US$6.3Bn in capital that is intended to back the fund’s strategy of ’mid-market European company buyouts and corporate carve-outs’ that aim to buy promising companies and build them through optimisation of their operations. 
Headquartered in Bocholt, Germany, and trading for more than 125 years, Flender supplies gearboxes, couplings and generators for industrial and wind power applications, including in the maritime and offshore energy sectors.

"With more than 8,000 employees across 34 countries, Flender operates a global manufacturing, assembly and service network and holds a leading position in drivetrain technology for wind turbines," the company claims.
Carlyle carved out Flender from Siemens in 2021, and said it has "partnered closely with management to lead the company’s successful transition to an independent standalone business" in the five years since.

"During this period, Flender strengthened its leadership position in wind and industrial drive technology, expanded its global service network, invested in innovation and operational capabilities, and further enhanced its international footprint and manufacturing platform," according to Carlyle.

Triton Partners lists current and past investments including RENK Group, Trench Group and FairWind among its bona fides for familiarity with the market.

“Flender is at the core of Triton Partners’ investment strategy. The company operates in a sector where Triton has strong expertise and a successful track record in similar industrial and aftermarket businesses,” Triton mid-market fund managing partner and co-head Claus von Hermann, and Triton Partners advisor Jaime Legeren said. 

Triton Partners claims it has many years of experience in applying its "in-depth value creation approach across companies in the industrial tech sector supported by the Accelerator Unit, one of Europe’s largest value acceleration teams in the industry". 

The Triton Fund 6 has already reportedly invested in maritime cargo and load-handling specialists MacGregor, among other companies.
