The flat-rolled producer said it is using the proceeds to refinance a substantial portion of its current debt and to provide working capital. 

"Big River Steel is extremely proud of the overwhelming support shown by the financial community and others as we achieved another significant milestone in the growth of our company," Big River chief executive Dave Stickler said. "Our ability to attract this amount of capital so early in our operating life is a testament to the hard work of our employees and our lead technology provider, SMS group." 

The new financing comes from US$600 million in corporate bonds; a six-year, US$400 million term loan; and a US$225 million asset-based lending facility.
