Moody’s Corp. [stock MCO][/stock], parent to the credit rating agency Moody’s Investors Service, updated guidance for 2010 earnings and revenue in a Securities and Exchange Commission filing on Thursday. The company now expects full-year 2010 revenue to increase approximately 13% versus 2009, with full-year 2010 diluted earnings per share to be in the range of $2.08 to $2.14 versus previous guidance of $1.90 to $1.96. “The full-year 2010 operating margin is expected to remain in the high-thirties percent range,” states the filing. “This reflects previously planned regulatory and technology spending, headcount additions and incremental expense associated with the stronger full-year outlook.” The corporation sees the uptick mainly from strong bond market issuance in the fourth quarter 2010. Moody’s Investors Service rates the risk of the bonds. There is also a growing demand for more software projects coming from customers of technology subsidiary, Moody’s Analytics. The updated guidance also includes recent change to both foreign and domestic tax codes that provide a more profit-friendly environment to the company. Moody’s Corp. will release final fourth-quarter and full-year results before the start of NYSE trading on Feb. 3. Jacob Gaffney is the editor of HousingWire. Follow him on Twitter @JacobGaffney.
