Weir Group, the Glasgow-based global mining and engineering FTSE 100 firm, said on Thursday it has priced an offering of Australian $400 million senior notes.

Weir said net proceeds of the notes are intended to partly fund the previously announced acquisition of Mining Software Holdings Pty Ltd (Micromine) of Perth, Australia.

In a stock exchange statement on Thursday, Weir said: “The Weir Group PLC has successfully priced an offering by its wholly owned subsidiary, Weir Group (Australian Holdings) Pty Limited (ABN 57 090 873 117), comprising Australian $400 million in aggregate principal amount of senior notes due 2031.

“The Notes will be guaranteed by the Company and Weir Group Inc., a US incorporated, wholly owned subsidiary of the Company.

“The net proceeds of the Notes are intended to partly fund the previously announced acquisition of Mining Software Holdings Pty Ltd (Micromine) …

“The Notes are priced at a spread of SQ ASW+165bps and will have a coupon of 5.200% per annum. The closing of the Notes offering is scheduled to be completed on or about October 23, 2025 and is subject to customary conditions.”

Weir chief financial officer Brian Puffer said: “We are delighted with the positive response to the Group’s Australian dollar syndicated bond offering.

“The proceeds will partly replace the existing bridging loan established for purposes of the Micromine acquisition.”
