AIB has said that it is facing challenges due to difficult market conditions and the slowdown in economic growth.
The bank says the relative strength of the euro will have approximately a 3% adverse effect on earnings.
It says it expects earnings per share to be down by 6% in the first half of this year compared to the same period in 2007.
AIB also says demand for loans is down, but it still anticipates growth of around 10% in this area during 2008.
