THE WEIR GROUP PLC

PRIVATE PLACEMENT DEBT ISSUANCE

16 February 2012

The Weir Group PLC today announces the issue of US$1bn of seven year (US$210m), ten year (US$590m) and 11 year (US$200m) senior unsecured fixed rate notes at an average interest rate of 4.16%. The proceeds will be used to repay the US$380m bridge facility previously arranged as part of the finance facilities for the acquisition of Seaboard Holdings Inc., to fund the completion of the Novatech acquisition and repay borrowings under the existing US$800m revolving credit facility, which continues to be available to the Group. The issuance follows the Group's successful US$250m debut in the private placement market in January 2010.

Weir Group Finance Director Jon Stanton commented: "We are delighted to have been able to source further and substantial long term finance at such attractive levels whilst continuing to diversify our funding sources. These funding arrangements provide us with enhanced flexibility to deliver our organic growth strategy and pursue our acquisitions agenda in line with our disciplined financial criteria."
