Private equity firm Rubicon Partners has acquired Erodex Graphite Systems Limited, a Halesowen-headquartered manufacturer and global supplier of carbon and graphite products used primarily in turbine blades and aerofoil structures. Business Sale Report reported on the deal, confirmed on 25 March 2026, which sees the company acquired from its family shareholders.

Founded in 1973, Erodex Graphite Systems operates through two divisions: one manufacturing and supplying carbon and graphite parts for a range of industries and ancillary products for the EDM sector, and another manufacturing carbon brush and associated accessories.

The firm has in-house design, tooling, and manufacturing capabilities, with machine shops in both the UK and US. It is best known for its premium graphite electrodes and brass tubes supporting global OEM and Tier 1 manufacturers.

In the year to 28 February 2025, the company reported turnover of slightly more than £20m (€23.2m), up from £18.7m (€21.7m) the previous year, while operating profits increased from £2.5m (€2.9m) to £3.4m (€3.9m).

The acquisition marks Rubicon Partners' 85th industrial investment and its second investment through Rubicon Partners Fund VI SCSp, a fund targeting mid-market businesses with an enterprise value of up to £200m (€232.2m). Rubicon has previously made seven investments in the aerospace sector, including Farsound Aviation, Attewell and Invotec.

Following the acquisition and the retirement of the family shareholders, operations director James Kirk will step up to CEO, alongside CFO Raj Rainu, to drive the next phase of the company's international growth in partnership with Rubicon.
