Orders below €4.40 in an initial public offering for AIB risk missing out, the bank said in a statement today.
The bank yesterday further revised the price guidance for its stock market listing to between €4.30 to €4.50 with order books covered throughout the range.
The price range was first narrowed to €4.20 to €4.60 on Tuesday when order books were covered in the upper half.
This indicates that the Government was set to net at least €3 billion from the sale of a 25% stake.
The advisors yesterday said the offer to retail investors or ordinary buyers was closed and they had been allocated 10% of the shares which will be sold.
The offer to institutions closed at noon today.
The flotation will proceed at 8am on Friday morning when AIB shares will be listed on the Main Securities Market of the Irish Stock Exchange.
