April 25 (Reuters) - Credit rating agency Moody's Corp reported a stronger-than-expected quarterly profit, driven by higher income from its analytics unit.
Net income attributable to Moody's rose to $218 million, or $1 per share, in the first quarter ended March 31, from $188.4 million, or 83 cents per share, a year earlier.
On an operating basis, the company earned 97 cents per share, above analysts' average estimate of 91 cents, according to Thomson Reuters I/B/E/S.
Revenue increased 5 percent to $767.2 million but fell short of the average analyst estimate of $770.2 million.
Revenue at Moody's analytics division, which sells financial research and data for assessing risk, rose 15 percent to $241.4 million, helped in part by the company's acquisition of Amba Investment Services.
The analytics department has helped Moody's weather a slowdown in bond issuance. Bond rating still forms the bulk of Moody's revenue and that unit's revenue rose less than 1 percent to $525.8 million.
The global bond markets, which hit record highs last year due to historic low interest rates, were muted during the first two months of the year.
Moody's along with Standard & Poor's Ratings Services, and Fitch Ratings, owned by Fimalac SA's, have a 95 percent share of the credit rating market.
McGraw Hill Financial Inc, which owns Standard & Poor's, reports results next week.
Moody's reaffirmed its full-year forecast for earnings of $3.90 to $4.00 per share and revenue growth percentage in high-single digits.
Moody's shares, which have risen about 45 percent in the year to Thursday's close, were little changed at $79.33 on the New York Stock Exchange on Friday.
