What Castings does

Castings P.L.C. is a UK-based public limited company (London Stock Exchange listed, registered number 00091580) founded in 1835 that operates as a market-leading iron casting and machining group supplying commercial vehicle original equipment manufacturers (OEMs) in Europe and export markets. The group comprises three iron foundries—Castings P.L.C. in Brownhills (West Midlands), William Lee Limited in Dronfield (Derbyshire), and Castings Ductile in Scunthorpe—together with one CNC machining operation (CNC Speedwell Limited, Brownhills), employing over 1,000 people in the UK. For the 2026 financial year, the group generated £173m in revenue, sold 41,500 tonnes of castings against a nameplate foundry capacity of 70,000 tonnes per annum, and reported profit before tax of £10.3m.

The company's core technology centres on iron casting and CNC machining. It produces five primary material grades—Spheroidal Graphite Iron (SG Iron), Ductile SiMo Iron, Ni-Resist Iron, Austempered Ductile Iron (ADI), and Grey Iron—across a part weight range from 0.15 kg up to 7 tonnes. Production assets include four Disamatic moulding machines, three horizontal green sand moulding machines, and an extensive CNC machining fleet (over 100 machines across vertical twin/single spindle, horizontal FMS, five-axis, and turning configurations), supplemented by an in-house £15m logistics centre, heat treatment, surface treatment, assembly, and warehousing capabilities. Engineering services include ESI ProCast simulation, 3D light scanning, topological optimisation, prototyping, and casting design assistance. The group is certified to IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, and TISAX.

Castings operates a B2B custom manufacturing business model with quote-based pricing and direct enterprise sales to commercial vehicle OEMs. Revenue derives from hardware sales of iron castings plus professional and managed services covering CNC machining, assembly, heat treatment, surface treatment, warehousing, and logistics. The share register is dispersed, with major institutional shareholders Threadneedle Asset Management (17.05%) and Aberforth Partners (15.32%) holding the largest positions. FY2026 capital expenditure of £20.5m (up 55% year-on-year) and operating cash flow of £25.1m indicate an ongoing reinvestment cycle funded entirely from internal cash generation.

Direct peers

• East Jordan Iron Works: East Jordan Iron Works is a US iron foundry producing a wide range of ductile and grey iron castings for commercial vehicles, infrastructure and industrial markets. Comparable to Castings PLC in iron-casting process technology and medium-batch commercial-vehicle component supply.
• Bradken: Bradken is a global manufacturer of large, complex iron and steel castings for mining, infrastructure, rail and heavy-industrial markets. Comparable to Castings PLC in core foundry technology and engineered castings capability, though Bradken is more diversified across heavy-industrial end markets.
• Doncasters Group: Doncasters is a UK-based precision castings and machining group serving aerospace, industrial gas turbines and commercial-vehicle markets. It is directly comparable to Castings PLC as a UK-headquartered, vertically integrated casting-and-machining business competing for similar high-specification OEM work.
• Waupaca Foundry: Waupaca Foundry is one of the largest iron foundries in North America, producing ductile, grey and compacted graphite iron castings for automotive, commercial vehicle and industrial markets. It is the closest international comparability peer to Castings PLC in terms of product mix (iron castings supplied to commercial-vehicle OEMs) and vertical integration into machining.
• Charlotte Pipe and Foundry: Charlotte Pipe and Foundry is a US iron foundry with significant foundry capacity and integrated casting operations serving plumbing, infrastructure and industrial markets. Comparable to Castings PLC in iron-casting process know-how and vertical integration, although more skewed toward pipe and infrastructure end uses.
• CIREX Foundry: CIREX is a Dutch iron foundry producing complex ductile and ADI castings primarily for commercial-vehicle and industrial OEMs. It is a direct European competitor to Castings PLC, with similar material expertise (including ADI) and shared exposure to European commercial-vehicle customers.
• Halberg Guss: Halberg Guss is a leading German iron foundry producing ductile and grey iron castings for commercial-vehicle, rail and industrial OEMs. It competes with Castings PLC in the European commercial-vehicle OEM supply base and operates a similar mix of high-volume moulding and downstream machining.

Broad incumbents

• McWane: McWane is a US privately-held group of iron foundries producing ductile iron pipe, fittings and castings for water infrastructure and industrial markets. Comparable to Castings PLC in iron-casting technology and vertical integration, but materially larger and more infrastructure-focused rather than commercial-vehicle focused.
• Georg Fischer: Georg Fischer (now GF) is a Swiss-listed industrial group with a long history in iron and steel casting alongside its larger piping systems business. It is comparable to Castings PLC on the casting side but operates as a much larger, more diversified industrial incumbent rather than a focused iron foundry.

Regional players

• Bibby Ste-Croix: Bibby Ste-Croix is a Canadian iron foundry producing ductile iron castings for water, infrastructure and industrial markets. Comparable in iron-casting process and material expertise to Castings PLC, but operates primarily in North America rather than competing directly in Castings' European OEM base.
