                           Allied Irish Banks, p.l.c.

                                 Trading Update





Allied Irish Banks, p.l.c. ("AIB") (NYSE:AIB) is issuing the following update on
trading following a review of performance in the year to date. All trends in
this update are in constant currency terms.



Since issuing guidance in February 2006 business in all our principal franchises
has been strong and these positive trends are being sustained. Customer demand
is buoyant and both the pipelines of new business and their high levels of
conversion at good rates of return on capital underpin our confidence in the
future. Asset quality is very strong and recoveries of impaired loans are
particularly high in the year to date.



Productivity continues to improve and we are targeting income growth to exceed
cost growth at enterprise and individual division level. Economic conditions in
our international and domestic markets are good and create a very positive
environment for us to develop high quality business. We continue to invest
heavily in our people and systems to underpin and sustain profitable growth. The
investment programme in our operations is also designed so that we are well
positioned and prepared to meet industry wide regulatory requirements.



Profit is expected to increase in each of our operating divisions this year. We
also anticipate a good increase in the contribution from our investment in M&T.



For the full year 2006, we are now targeting mid to high teens growth in
adjusted basic earnings per share (EPS).* This guidance is relative to the 2005
number of 145.9c. The rate of EPS growth for the interim 6 months to June is
expected to exceed that of the full year's due to a level of impaired loan
recoveries in the current period that we consider to be exceptional.



Our planned growth will be supported through a combination of capital we
generate internally and capital we select from a suite of other available
sources. Our funding profile is conservative and was recently boosted by the
successful and efficient raising of EUR3.5bn in the fixed income market.



* Excludes profit on Bankcentre sale and development, profit on Aviva / ARK Life
transaction and hedge volatility under IFRS





REPUBLIC OF IRELAND DIVISION

Our domestic retail and commercial banking franchise is performing strongly. A
higher interest rate environment is expected to temper rather than materially
reduce customer demand and we are now targeting loans to increase this year by
around 25%, higher than previously guided in February. We expect growth in
customer deposits to be around 15%. Competition remains intense although its
impact is as anticipated. Our recently revised suite of products and services
further underpins the resilience and potential of our market position.



We have agreed a framework for performance related pay with our staff that sets
us apart from our peers. This action reflects our confidence in the future and
ensures we continue to attract and retain key people to sustain long term
growth. It increases the proportion of variable costs and together with other
discretionary investments in our business will mean an above trend growth in
costs this year. However, we expect the rate of income growth to be greater than
the rate of increase in costs.





UK DIVISION

In Great Britain our focus on chosen business sectors continues to deliver high
quality growth. The consistent high grade customer service we provide is
creating an abundance of opportunities and there is strong momentum in both
loans and deposits. Our aggressive business development plan is being executed
by high calibre teams in which we continue to invest and supplement with
additional skilled people. Branch and office locations are being upgraded or
relocated to ensure we optimise the potential of our market position.



First Trust in Northern Ireland is performing well and in line with
expectations.



Full year loan growth for the division is expected to be over 20% and deposits
are expected to grow by around 15%.





CAPITAL MARKETS

Corporate Banking, which comprises over half this division's profit, is enjoying
another outstanding year. We have a proven ability to identify and establish
premium positions in attractive international markets from which we derive over
70% of Corporate Banking's profit. This ability, allied to a strong domestic
franchise is the hallmark of Corporate Banking's consistent outperformance. We
are targeting loans to increase by around 20% this year and expect the pattern
of strong profit growth to continue.



Global Treasury is performing well. Performance in our customer business is well
distributed and robust across the major product lines of foreign exchange, cash
management and interest rate risk management. Performance in our wholesale
business is in line with expectations with our bond management activities a
highlight.



Goodbody Stockbrokers and our corporate finance teams are notable contributors
to an overall good performance anticipated in Investment Banking.





POLAND DIVISION

A year of strong profit growth is expected in Poland.



Buoyant demand for our best-in-class investment funds products is a particular
highlight. Momentum in the latter months of 2005 has continued and inflows from
new and existing customers are running at record levels.



An increase in our loan book of around 10% is anticipated with good demand
evident for personal loans. Demand for local currency mortgages is beginning to
recover which we see as a welcome development. The business lending environment
is gradually improving and while liquidity amongst corporates is still high
there is a positive outlook for investment spending which should increase loan
demand.



In the savings market, customers are primarily focused on investment funds; we
expect a single digit increase in our deposits this year.





M&T BANK CORPORATION

A good contribution is expected again in 2006 as M&T maximises opportunities in
a relatively lower growth environment. In the first quarter of this year, M&T
once again exceeded market consensus. Both efficiency gains and further
improvements in asset quality were highlights of performance.





MARGINS

In line with our guidance at the announcement of our 2005 results in February we
continue to expect around 20 basis points of reduction in our net interest
margin this year. The causes are the same as they have been for some time -
loans growing faster than deposits, lower reinvestment rates for customer
account funds, business mix and competition.





NON INTEREST INCOME

We are now targeting a significant increase of around 12% in 2006. In Poland,
asset management, stockbroking and payment processing fees are all growing
strongly. Activity levels and business pipelines are also well up on last year
in our Irish corporate finance business.





COSTS

We are confident that we will again achieve our core objective of maintaining a
positive gap of at least 3% between income and cost growth. This year we expect
an above trend cost increase of around 9%.



In this time of exceptional opportunity and income buoyancy we consider it
prudent to invest so that the long term health of our business is assured.
People recruitment and reward, building common operating systems and a resilient
risk, compliance and corporate governance framework across the enterprise are
all essential ingredients vital to achieving this goal. In the event of an
income slowdown, the pace of investment would be moderated without impairing our
business.





ASSET QUALITY

All leading indicators of asset quality are solid. We remain vigilant in our
assessment and management of risk; while this is an exceptionally benign credit
environment, there are currently no trends or developments that lead us to
foresee an imminent deterioration. We now expect the bad debt provision charge
in 2006 not to exceed 15 basis points of average loans. As referred to earlier
in this update, very high non recurring recoveries in the first half are likely
to mean a lower charge in the interim period to June.





NOTE

Group results for the interim period to 30th June 2006 will be announced on 1st
August 2006.
