UK-based engineering company Weir has announced the completion of the previously announced acquisition of Micromine, a provider of mining software solutions, for an enterprise value equivalent to £624m ($840m).
Micromine is known for its advanced software spanning the entire upstream mining value chain including exploration, mine design, planning and operations for various mining applications.
The transaction follows the initial agreement disclosed in February 2025.
Weir plans to integrate Micromine’s offerings with its MOTION METRICS and NEXT intelligent solutions, aiming to establish a digital solutions portfolio for the mining industry. Until the integration is complete, Micromine will be reported within the ESCO Division.
Kristen Walsh, formerly the regional managing director of Minerals APAC, will lead the new Digital Solutions division as president.
Andrew Birch, Micromine’s current CEO, will continue to advise Weir for up to one year to support the transition.
The addition of Micromine is projected to enhance Weir’s operating margins by approximately 25 basis points in 2025.
The company anticipates around £16m in one-off integration and acquisition-related costs as exceptional items over 2025 and 2026.
The funding of this acquisition is also expected to result in an increase in interest costs of around £25m for the year.
Weir CEO Jon Stanton said: “Weir’s mission is to deliver mining technology for a sustainable future, helping the mining industry produce the metals needed to power the global energy transition. Digital has a big part to play, and Weir is innovating and investing in digital solutions to make mining smarter, more efficient and sustainable.
“Bringing together Micromine with our existing digital technologies, our vision is to create a digital platform that helps our customers optimise their performance at each step along the mining value chain. This is about bringing together Weir’s knowledge, capabilities and expertise to create sector-leading digital solutions for the mining industry.”
