The company had a profit of $2.76 billion in the second quarter of June 2008, IBM said in a statement.
However, the total revenue decreased 13 per cent to $23.3 billion in the latest quarter from $26.82 billion in the corresponding year-ago period.
"As a result of our strategic transformation, we have a very strong business model that is delivering superior earnings, cash and client value.
"We have continued our strategic investments in Smarter Planet solutions, business analytics and next generation data centres. As a result we are optimistic about how IBM is positioned to make the most of current growth opportunities as well as those that emerge as the economy recovers," IBM chairman, president and CEO Samuel J Palmisano said.
IBM revised its guidance for the full-year 2009 earnings to at least $9.70 per share compared with its previous expectation of at least $9.20 per share, the statement said.
The company expects full-year 2009 pre-tax income for its software segment to grow at a double-digit rate and reach about $8 billion.
