Lithium producer Pilbara Minerals (ASX:PLS) has executed transaction documents for a $1 billion revolving credit facility with a group of domestic and international banks. The lenders include BNP Paribas, Australia Branch, Commonwealth Bank of Australia, National Australia Bank, The Hongkong and Shanghai Banking Corporation, Sydney Branch, Societe Generale, Sydney Bank, and ING Bank. Pilbara Minerals says the facility will increase its financial flexibility, with the funds to be used for refinancing and general working capital purposes subject to drawdown conditions. To facilitate financial close of the facility, the $8.64 billion market capitalised company will repay any outstanding amounts under its existing 10-year $250 million debt facility with Export Finance Australia and the Northern Australia Infrastructure Facility, as well as its five-year US$113 million ($168.28 million) syndicated debt facility.
