Moody’s Investors Service has upgraded the Memphis-Shelby County Airport Authority, TN’s general airport revenue bonds to A2 from A3, and changed the rating outlook to stable from positive. Moody’s rates the authority’s 2010 and 2011 series revenue bonds, of which around $195 million remain outstanding. The upgrade to A2 was supported by the sustained track-record of positive enplanement growth at the Memphis International Airport since fiscal year 2016 that has demonstrated the fundamental demand for the airport and has supported improved financial performance.
