The ratings were also removed from CreditWatch with positive implications, where they were placed on March 11, 2004, following the announcement that Hornbeck would issue six million shares of common stock in an IPO. The outlook is now stable. Mandeville, La.-based Hornbeck currently has $175 million of debt. "The ratings upgrade reflects Hornbeck's improved liquidity and financial flexibility following its IPO," said Standard&Poor's credit
