The company posted first-quarter earnings per share of $1.52, up from $1.23 a share in the year-earlier period.
Revenue for the quarter came in at $19.809 billion, against the comparable year-ago figure of $20.12 billion.
Analysts expected Citigroup to report earnings of $1.39 a share on $19.82 billion in revenue, according to a consensus estimate from Thomson Reuters.
Citi announced in February it cut Chief Executive Michael Corbat's pay by about 7 percent in 2014, a year in which the bank's profit nearly halved due to higher legal costs and a slump in bond trading.
Year to date, bank's stock is slightly lower, roughly in line with the performance of the S&P 500's financial sector.
