VIRGINIA BEACH, Va. (Nov. 10, 2011) — Amerigroup Corporation (NYSE: AGP) announced today the pricing of $400 million in aggregate principal amount of 7.5% senior notes due 2019, through Goldman, Sachs & Co. as sole underwriter. The notes mature on November 15, 2019. The notes will bear interest at a rate of 7.5% annually payable on May 15 and November 15 of each year, beginning on May 15, 2012.
