Weir Group: Robust Aftermarket Demand Supports Continued Margin Expansion

Weir is a mining technology company with leading positions in highly engineered, mission-critical equipment for mineral processing. The group concentrates on slurry handling and comminution systems—areas where reliability, wear performance, and engineering support are more important than price. These products sit at the heart of continuous mining operations, and Weir has built a large installed base that generates resilient, high-margin aftermarket demand. Around 80% of revenue comes from replacement parts and consumables required to keep mines running, giving the business a growth profile backed by recurring revenue.
