US cleantech and other investors made their presence felt in a record year of financing and M&A in the global mining and metals technology arena in 2025. They constituted half the more than 130 investors who led US$1.19 billion of equity financing, which was a decent chunk of the plus-$4.8 billion of deals in the space last year.
Mergers and acquisitions accounted for more than $3.69 billion of that deal total, including US-based Wabtec’s $1.78 billion acquisition of the former Olympus Corp business, Evident Scientific Inspection Technologies. Weir’s $800 million acquisition of Micromine and Caterpillar’s $735 million purchase of RPMGlobal also inflated the total.
The $4.8 billion of financing and M&A surpassed the previous $3.03 billion high for mining and metals tech transactions in 2021. That was the year Bentley Systems took out Seequent and Sweden’s Sandvik bought Deswik. Australian mining software and sensor firms figure prominently in the biggest deals in that space over the past five years (see list below).
The $1.19 billion of financing announced in 2025 compared with $738 million in 2024.
