               Financial Institutions, Inc. Reports 2003 Earnings



    WARSAW, N.Y., Jan. 22 /PRNewswire-FirstCall/ -- Financial Institutions,
Inc. (Nasdaq: FISI) today reported net income of $14,247,000 for the year
ended December 31, 2003 compared to $26,456,000 in 2002.  Diluted earnings per
share for the year 2003 were $1.13, down from $2.23 per share in 2002.  Fourth
quarter 2003 net income was $2,246,000 compared to $6,271,000 for the
comparable period in 2002.  Diluted earnings per share were $0.17 for the
fourth quarter of 2003 compared to $0.53 for the same period in 2002.  Return
on average common equity was 7.65% for the twelve months of 2003 compared to
17.01% last year.  The most significant impact on fourth quarter and full year
2003 financial results was the provision for loan losses, which totaled
$8,327,000 for the fourth quarter 2003, an increase of $5,848,000 over the
$2,479,000 provision for loan losses for the fourth quarter of 2002.  For the
twelve months of 2003 the provision for loan losses totaled $22,526,000, an
increase of $16,407,000 over the $6,119,000 provision for loan losses for the
2002 period.

    Peter G. Humphrey, President and CEO of Financial Institutions, Inc. (FII)
stated: "Credit quality issues made 2003 a challenging year for the Company.
High levels of nonperforming loans with associated charge-offs and increases
to the allowance for loan losses significantly impacted our financial results.
In addition, increased regulatory oversight is in place in the form of written
agreements at our two national banks.  We have committed substantial resources
to strengthening the credit administration and underwriting functions.  The
year also saw market interest rates reaching historically low levels and in
that challenging environment our net interest income was stable at $75
million.  Noninterest income increased $4 million to $26 million led by a $1.8
million increase in mortgage banking income.  We are pleased with the results
of our de novo branching with recently opened offices making significant
contributions to a 6% or $110 million increase in our total deposits."

    Nonperforming assets increased $0.2 million during the fourth quarter of
2003 to $52.1 million at December 31, 2003 compared to $51.9 million at
September 30, 2003 and increased $13.7 million from $38.4 million at December
31, 2002.  Net loan charge-offs for the fourth quarter of 2003 were $8.3
million, or 2.44% of average loans, compared to $1.3 million, or 0.40% of
average loans, in the fourth quarter of 2002 and were $15.1 million, or 1.11%
of average loans, for full year 2003 compared to $3.7 million, or 0.30% of
average loans, in 2002.  Nonperforming agricultural credits, principally dairy
farms, increased $4.4 million in the fourth quarter of 2003 and have increased
$10.3 million since December 31, 2002.  Total nonperforming agricultural loans
were $22.1 million at December 31, 2003 or 9.40% of total agricultural loans.
Borrower cash flows in the dairy industry have recently improved due to some
stabilization and upward movement in milk prices.  Commercial and commercial
mortgage loans represented $6.0 million of fourth quarter 2003 net charge-offs
and $11.3 million for full year 2003.

    The ratio of the allowance for loan losses to nonperforming loans was 56%
at December 31, 2003 compared to 58% at December 31, 2002 and 57% at September
30, 2003.  The ratio of the allowance for loan losses to total loans increased
to 2.16% at December 31, 2003 compared to 1.64% at year end 2002 and 2.12% at
September 30, 2002.  The provisions for loan losses were $8.3 million for the
fourth quarter of 2003 and $22.5 million for the twelve months ending December
31, 2003.

    For the fourth quarter of 2003, net interest income decreased 2% to
$18,927,000, compared to $19,258,000 for the fourth quarter of 2002.  Net
interest income in 2003 was $75.5 million compared to $75.9 million in 2002.
Net interest margin was 3.95% for the year ended December 31, 2003, a drop of
42 basis points from the 4.37% level for the same period last year.  Growth in
average earning assets of $183 million, or 10%, served to partially offset the
fall in net interest margin.  The growth in average earning assets reflects an
average increase of $123 million in the Company's loan portfolio.  The
principal funding source for the average earning asset growth was deposits,
with the average for the year ended December 31, 2003 increasing $194 million
or 12% over the average for the same period in 2002.  Net interest margin
declined in 2003, as general market interest rates declined to historically
low levels.  As overall interest rates have fallen the Company's yield on
earning assets have declined more rapidly than the cost of funds.  Lost
interest on the higher levels of nonaccrual loans have also contributed to the
decline in net interest margin.  For the fourth quarter of 2003 net interest
margin was 3.96% compared to 4.21% in the same quarter last year.

    Noninterest income increased 5% in the fourth quarter of 2003 to
$6,751,000 from $6,408,000 for the fourth quarter of 2002.  For the twelve
months ending December 31, 2003 noninterest income was $26,072,000 compared to
$22,189,000 for the same period last year.  The increase in noninterest income
in 2003 compared to 2002 is primarily attributed to an increase in mortgage
banking activities of $1.8 million, growth in deposits and the related service
fees of $0.9 million, and an increase in net security gains of $0.8 million.
The increase in mortgage banking revenues corresponds with the increase in
residential mortgage refinancing activity resulting from the historically low
interest rate environment.  The Company sells most fixed rate newly originated
and refinanced mortgage loans in the secondary market and retains the
servicing rights.  The Company's loan servicing income portfolio was $385
million at December 31, 2003 compared to $356 million at December 31, 2002.

    Noninterest expense for the fourth quarter of 2003 totaled $15,404,000
compared with $14,438,000 for the fourth quarter of 2002.  For the twelve
months ending December 31, 2003, noninterest expense was $60,823,000 compared
to $53,049,000 for the same period last year.  The increased level of
noninterest expense is attributed to higher credit collection costs, costs of
opening new branch offices and costs for additional lending and credit
administration staff.  The additional noninterest expenses, coupled with a
slowing of revenue growth, are the principal factors in an increase in the
Company's efficiency ratio to 55.73% for the twelve months ended December 31,
2003, compared to 50.62% for the same period a year ago.

    At December 31, 2003 the Company's total shareholders' equity was $183
million compared to $178 million a year earlier.  During the fourth quarter of
2003 the Company completed a debt-financing plan that raised $25 million.  A
portion of the proceeds of that financing were contributed as capital to the
Company's National Bank of Geneva and Bath National Bank subsidiaries allowing
those banks to meet higher capital ratios that were required to be met by
March 31, 2004 in agreements imposed by their regulator.

    At December 31, 2003 the Company had total assets of  $2.174 billion, an
increase of 3% from $2.105 billion at December 31, 2002.  Total deposits were
$1.819 billion at year-end 2003, compared with $1.709 billion a year earlier.
Book value per common share at December 31, 2003 was $14.81, an increase of 2%
from $14.46 at December 31, 2002.  Total common dividends of  $0.64 per share
were declared in 2003, an increase of $0.06 or 10% over the $0.58 per share
declared in 2002.
