                           Allied Irish Banks, p.l.c.

                                 Trading Update


Allied Irish Banks, p.l.c. ("AIB") (NYSE:AIB) is issuing the following update on
trading before its year end close period. Please note that all trends in this
update are in constant currency terms and relative to 2004

pro-forma IFRS results.


2005 has been a year in which we have achieved strong performance across the
enterprise.


We expect the consistent, recurring and sustainable nature of our business to be
underlined in each of our operating divisions by:


  - Double digit profit growth

  - Income growing faster than costs, resulting in lower cost / income ratios

  - Market share gains in targeted sectors and products.

Our partnership with M&T continues to flourish and we expect this to be again
reflected in its profit contribution this year.


Earnings momentum is driven by our franchises being located in outperforming
economies which underpin high volume, high quality growth. Momentum is further
assured by very robust asset quality. Our growth is built on customer demand,
most clearly illustrated by expected record levels of deposit growth in both our
Irish and British franchises. We actively manage our sound capital and funding
positions so as to support the deep supply of high quality growth opportunities
we continue to identify.


At our interim results in August, we guided earnings per share (EPS) in 2005 in
a range of 140c - 142c. Performance in our franchises since then now leads us to
target the upper end of that range. This compares to the pro-forma IFRS EPS in
2004 of 127.1c. Guidance for 2005 assumes zero volatility due to accounting
hedge ineffectiveness under IFRS.


We continue investing to support and sustain growth. Significant financial and
people investment is being made in our risk, compliance and governance
framework. Our work programmes to ensure we meet our extensive regulatory
requirements are on track. The resourcing and restructuring of our enterprise
wide approach to operations is in implementation and we expect this to further
bolster our business capability.



REPUBLIC OF IRELAND DIVISION

Buoyant, high quality volume growth has again been a feature of our Irish retail
and commercial banking business this year. Loans are expected to grow by around
25% and reflect further gains from our long held position as the number one
business bank in the market. Our mortgage growth is broadly in line with the
market which is being achieved while ensuring new business written is of the
same high quality as the back book. The effectiveness of our customer
relationship management approach is underlined by the high teens deposit growth
anticipated this year.


Profit at Ark Life - which will shortly begin its partnership with Aviva's Irish
subsidiary, Hibernian - is expected to be up on last year.



GREAT BRITAIN AND NORTHERN IRELAND DIVISION

In Great Britain our focus on chosen mid market business sectors is driving
strong profit growth. A growing number of customers are selecting us as their
bank of choice, attracted by our differentiated and consistent service offering.
Our growth is supported by recruitment and investment in people and business
infrastructure. Quality is underpinned by our long established practice of
avoiding exposure to higher risk sectors, those which are heavily commoditised
and those in which we do not hold an advantage over our competitors with larger
scale and market coverage.


In Northern Ireland solid profit growth is anticipated on the back of strong
increases in both loans and deposits.


Overall in the division we expect loan growth of around 25% and deposits to
increase by around 18%.



CAPITAL MARKETS DIVISION

Profit growth anticipated this year will again demonstrate the strength and
sustainability of this division. A key catalyst for growth is the expected
significantly increased contribution from Corporate Banking which represents
more than half the profit of Capital Markets division. Our domestic corporate
unit is performing satisfactorily and in particular, our international business
- which now comprises c. 70% of Corporate Banking's profit - is growing
strongly. We expect loans overall to grow by around 25% while remaining rigorous
in our assessment of loan quality and returns.


In Treasury we expect satisfactory revenues from customer activities. Our bond
management and interest rate trading units are performing well, while
maintaining low risk positions.


In line with expectations, Investment Banking is having a good year with a
particularly notable performance from Goodbody Stockbrokers and our Corporate
Finance teams.



POLAND DIVISION

Building on the strong recovery in 2004, the full year will reflect further
positive performance momentum.


The main drivers continue to be non interest income growth underpinned by market
share gains in investment funds and stockbroking, sustained tight cost
management and best in class asset quality.


Customer demand for savings products is heavily biased towards mutual funds in
the current lower interest rate environment. We are now a top 3 mutual fund
provider following growth of over 100% in funds under management this year. In
bank deposits we expect growth of around 3%. Loans are expected to be up by
around 2%, a little better than at the half year stage. Attainment of more rapid
growth continues to be challenging due to subdued business demand, combined with
our continued focus on lower risk local currency mortgages, in which we continue
to grow market share.



M&T BANK CORPORATION

At M&T we anticipate another year of good profit growth in 2005. A highlight of
performance in the first 9 months has been management's ability to contain costs
during a period of slow industry wide revenue growth. The efficiency ratio has
been reduced to 50% in the third quarter and productivity gains are being
complemented by very good asset quality.



MARGINS

Consistent with guidance at our interim results, the expected rate of reduction
in our net interest margin of around 20 basis points is unchanged. The causes
are also the same as previously advised - loans growing faster than deposits,
lower reinvestment rates for customer account funds, business mix and
competition.



NON INTEREST INCOME

An increase of around 4% is expected this year. Momentum in this income category
is affected by the inclusion of lending related fees under IFRS in interest
income. Corporate banking and card fees are notably higher sources of non
interest income in 2005.



COSTS

We expect an increase of around 7 - 8% in 2005. Regulatory costs continue to be
a significant factor. We are investing heavily in our business and people. We
will continue to do so at this time of widespread opportunity in our franchises.
Our focus remains on efficiency and improving productivity in which we are
making further progress this year.



ASSET QUALITY

Asset quality remains resilient and there has been no deterioration in any of
our portfolios. All leading indicators of loan impairment continue to be stable.
At our interim results we guided a loan loss charge of less than 20 basis points
of average loans for 2005 and stated that the lower charge in the first half was
exceptional. We now reiterate both aspects of that previous guidance.



NOTE

Group results for the year end 31st December 2005 will be announced on 22nd
February 2006.
