          Financial Institutions, Inc. Reports Second Quarter Earnings

WARSAW, N.Y. -- Financial Institutions, Inc. (NASDAQ:FISI) today reported that
second quarter 2003 net income was $3,650,000 compared to $6,644,000 for the
same quarter last year. Diluted earnings per share were $0.29 for the second
quarter of 2003 compared to $0.56 for the 2002 period. The most significant item
impacting second quarter 2003 results was a provision for loan losses of
$5,311,000, which represents an increase of $4,130,000 over the $1,181,000
provision for loan losses for the second quarter of 2002. The three-month period
ending June 30, 2003 also included a $538,000 write-down of a parcel of other
real estate owned.

Peter G. Humphrey, President and CEO of Financial Institutions, Inc. (FII),
said: "Second quarter 2003 results were adversely affected by further declines
in credit quality. The overall weak economic environment has contributed to an
increase in nonperforming assets. As indicated in previous quarters, the Company
has committed additional resources toward management of the Company's
nonperforming assets and strengthening the credit administration function. The
Company's net interest income and noninterest income levels are strong and we
remain focused on the execution of our strategic plan and long-term growth
strategy."

At June 30, 2003 nonperforming assets were $50.7 million compared to $38.4
million at December 31, 2002 and $12.3 million at June 30, 2002. The increase in
nonperforming loans since year-end includes an increase of $5.7 million in


                                       1


commercial loans, $2.2 million in commercial mortgage loans, and $4.6 million in
agricultural loans. Mr. Humphrey stated, "The extended weak economy continues to
adversely impact the cash flows of some of our commercial borrowers, most
notably at the National Bank of Geneva, as well as the valuation of collateral
supporting their loans. In addition, an extended period of low milk prices has
placed stress on several of our dairy industry borrowers and has resulted in an
increase in nonperforming agricultural loans, primarily at Wyoming County Bank.
Recently there has been favorable movement in the trend of milk prices. We have
made significant strides towards strengthening the Company's credit
administration function during the first half of 2003 and put in place workout
plans on our problem loans."

For the second quarter of 2003 net loan charge-offs were $2,227,000 or 0.66% of
average loans compared to $718,000, or 0.24% of average loans, in the same
period last year. The ratio of nonperforming assets to total loans and other
real estate was 3.70% at June 30, 2003 compared to 2.90% at December 31, 2002
and 0.99% a year ago. The provision for loan losses increased $4,130,000 over
the same period from a year ago reflective of the increased level of charge-offs
and nonperforming loans. The ratio of the allowance for loan losses to
nonperforming loans was 53% at June 30, 2003, compared to 58% at December 31,
2002 and 187% at June 30, 2002. The ratio of the allowance for loan losses to
total loans increased to 1.93% at June 30, 2003 compared to 1.64% at year end
2002 and 1.62% at June 30, 2002.

In the second quarter of 2003, net interest income increased 1.0% to $19,193,000
compared to $18,986,000 in the second quarter of 2002. Net interest margin was
3.98% for the second quarter of 2003, a drop of 41 basis points from the 4.39%
level for the same period last year.


                                       2


Growth in average earning assets of $211 million, or 11%, offset the fall in net
interest margin and produced the increased revenue. The growth in average
earning assets reflects average increases of $65 million in the Company's
investment portfolio and $148 million in loans. Net interest margin has declined
over the past year, as interest rates have declined to historically low levels.
The increase in nonaccrual loans has also contributed to the decline in net
interest margin in recent quarters.

Noninterest income increased 19% in the second quarter of 2003 to $6,160,000
from $5,157,000 for the second quarter of 2002. Mortgage banking activities,
which include gains and losses from the sale of residential mortgage loans,
mortgage servicing income and the amortization of mortgage servicing rights,
increased $677,000 to $951,000 in the second quarter 2003 from $274,000 for the
same period last year. The increase in mortgage banking revenues corresponds
with the increase in residential mortgage refinance activity resulting from the
historically low interest rate environment. The Company sells most newly
originated and refinanced mortgage loans in the secondary market. Growth in
deposits and related activity resulted in service charges on deposits increasing
$164,000 to $2,771,000 for the three months ending June 30, 2003 compared to
$2,607,000 for the same period a year ago.

Noninterest expense for the second quarter of 2003 totaled $14,947,000 compared
with $13,093,000 for the second quarter of 2002. As previously indicated,
$538,000 of the increase relates to the write-down of a parcel of other real
estate owned. Salaries and benefits have increased $529,000 primarily as a
result of additional staffing associated with the Company's new branch offices
and the expansion of the credit administration department. Occupancy and


                                       3


equipment costs have increased $373,000 due to the additional offices and
expansion of the Company's technology platform. These additional costs, coupled
with a slowing of revenue growth, are the principal factors in an increase in
the Company's efficiency ratio to 53.41%, compared to 51.05% for the same period
a year ago. Mr. Humphrey said, "Our strategic plan has identified opportunities
for expansion into markets where we believe our brand of banking will allow us
to achieve significant market share. During 2002 we opened offices in six new
locations. During the first half of 2003 we opened one additional branch and are
moving forward with plans to open two more during the second half of 2003. As we
invest in the future, the costs associated with expansion and the related
support structure have contributed to an increase in our efficiency ratio. We
expect that our operating measures will improve as these new offices come on
line and our credit-related costs decline as we work through our problem loans."

At June 30, 2003 the Company had total assets of $2.194 billion, an increase of
11% from $1.979 billion at June 30, 2002. Total loans at quarter end were $1.371
billion, an increase of $129 million, or 10%, over the same period last year.
Total deposits were $1.826 billion at the recent quarter-end, compared with
$1.608 billion a year earlier. Total shareholders' equity increased 13% to $186
million at June 30, 2003 from $164 million a year earlier. Book value per common
share at June 30, 2003 was $15.17, an increase of 15% from $13.23 at June 30,
2002.
