TORONTO, March 9, 2017 /PRNewswire/ - IAMGOLD Corporation ("IAMGOLD" or the "Company") today announced that it has priced a private offering of $400 million aggregate principal amount of senior notes due 2025 (the "Notes"). The Notes bear interest at 7.00% per annum and are being issued at a price of 100% of their face amount, providing the company with gross proceeds of $400 million. The offering of the Notes is expected to close on or about March 16, 2017, subject to customary closing conditions. Subject to the closing of the Notes, IAMGOLD will use the proceeds of the Notes towards the redemption of its $489 million of outstanding 6.75% Senior Notes due in October 2020 (the "Existing Notes") on or about April 2, 2017.

"Our four-year plan is to increase gold production to one million ounces and to significantly reduce costs," said Executive Vice President and CFO for IAMGOLD Carol Banducci. "While we continue to be very comfortable with our strong financial position today, reducing our long-term debt and extending the maturity date of our notes to 2025 improves our capital structure and supports our ability to fund our growth pipeline over the four-year horizon and beyond."

The Notes have not been and will not be registered under the United States Securities Act of 1933, as amended (the "Securities Act"), or the securities laws of any state and may not be offered or sold in the United States absent registration under the Securities Act or an applicable exemption from the registration requirements thereof. The Notes will be offered and sold in the United States only to qualified institutional buyers in accordance with Rule 144A under the Securities Act and outside the United States in reliance on Regulation S under the Securities Act. The Notes will be offered and sold in Canada on a private placement basis pursuant to certain exemptions from applicable Canadian securities laws.

This news release does not constitute an offer to sell or a solicitation of an offer to buy the Notes in the United States or any other jurisdiction, nor shall there be any sale of the Notes in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction or an exemption therefrom. This news release does not constitute an offer to purchase the Existing Notes. This news release contains information about pending transactions, and there can be no assurance that these transactions will be completed.
