                      ESB FINANCIAL CORPORATION REPORTS
                        SECOND QUARTER 2004 EARNINGS


Ellwood City, Pennsylvania, July 20, 2004 - ESB Financial Corporation (Nasdaq:
ESBF), the parent company of ESB Bank, today announced earnings for the
quarter ended June 30, 2004 of $0.22 per diluted share on net income of $2.4
million, which represents a 46.7% increase in net income per diluted share as
compared to earnings of $0.15 per diluted share on net income of $1.7 million
for the quarter ended June 30, 2003. The Company's annualized return on
average assets and average equity were 0.69% and 10.25%, respectively, for
the quarter ended June 30, 2004, compared to 0.49% and 6.57%, respectively,
for the quarter ended June 30, 2003.

For the six month period ended June 30, 2004, the Company realized earnings of
$0.45 per diluted share on net income of $4.8 million, which represents an
18.4% increase in net income per diluted share as compared to earnings of
$0.38 per diluted share on net income of $4.0 million for the same period in
the prior year.  The Company's annualized return on average assets and average
equity were 0.70% and 9.98%, respectively, for the six-month period ended June
30, 2004, compared to 0.60% and 8.04%, respectively, for the six months ended
June 30, 2003.

In announcing the results of operations for the quarter and the six months
ended June 30, 2004, Charlotte A. Zuschlag, President and Chief Executive
Officer of the Company and the Bank, stated, "We are pleased with the second
quarter and year to date results and the continued improvement in our net
interest margin over last year.  Our improved margin is due in part to our
decision to restructure and call a significant portion of the Company's fixed
rate trust preferred securities and a decline in repayments and amortization
of premiums on our investment portfolio. The Company remains focused on
improving net interest and non-interest income, while pursuing strategies to
grow and provide a sound investment return to our shareholders."

Consolidated net income increased $691,000, or 41.4%, to $2.4 million for the
quarter ended June 30, 2004, compared to $1.7 million for the same period in
the prior year.  This increase was the result of an increase in net interest
income, after the provision for loan losses, of $1.1 million and a decrease in

non-interest expense of $135,000, partially offset by a decrease in
non-interest income of $376,000 and an increase the provision for income
taxes of $218,000. Net interest income increased in the second quarter
primarily due to lower interest expense on deposits and borrowings, partially
offset by declines in interest income from loans and securities.  Included in
the decrease of non-interest income were decreases in fees from the sale of
loans, gains on the sale of available for sale securities and income from
joint ventures of $136,000, $331,000 and $286,000, respectively, partially
offset by increases to fees and service charges and prepayment fees on
mortgage loans of $130,000 and $217,000, respectively.

Consolidated net income for the six month period ended June 30, 2004, as
compared to the six month period ended June 30, 2003, increased $765,000, or
19.0%, to $4.8 million from $4.0 million.  This increase was primarily the
result of an increase in net interest income, after the provision for loan
losses, of $1.7 million and an increase in non-interest income of $128,000,
partially offset by an increase in non-interest expense and provision for
income taxes of $895,000 and $182,000, respectively. The increase in net
interest income after the provision for loan losses for the period ended June
30, 2004 was primarily the result of decreases in interest expense on deposits
and borrowings, partially offset by declines in interest income from loans and
securities and an increase in provision for loan losses of $270,000.  The
decrease in interest expense was enhanced by the call of a significant
portion of the Company's trust preferred securities early in the first quarter
of 2004.  Included in the increase to non-interest expense was a charge of
approximately $844,000 for the deferred debt issuance costs associated with
the redemption of a portion of the Company's subordinated debt in connection
with the call of the trust preferred securities.

The Company's total assets decreased by $4.0 million, or 0.3%, to $1.4 billion
at June 30, 2004. This decrease resulted primarily from a decrease in
securities of $23.8 million, or 2.6%, to $905.1 million, which was partially
offset by increases in cash and cash equivalents, loans receivable, Federal
Home Loan Bank Stock and prepaid expenses and other assets of $3.6 million, or
23.2%, $8.7 million, or 2.7%, $1.5 million, or 5.0%, and $5.4 million, or
87.5%, respectively.  The Company's total liabilities increased by $3.9
million, or 0.3%, to $1.3 billion at June 30, 2004. The increase in total
liabilities was primarily the result of an increase in borrowed funds of $21.6
million, or 3.3%, partially offset by a decrease in deposits of $17.4 million,
or 2.9%.  Total stockholders' equity decreased $7.9 million, or 8.1%, to $89.0
million at June 30, 2004, from $96.9 million at December 31, 2003.  The
decrease to stockholders' equity was the result of a decrease in accumulated
other comprehensive income of $9.5 million as well as increases in treasury
stock and unvested shares held by management recognition plan of $892,000 and
$181,000, respectively. These decreases were partially offset by increases to
additional paid in capital and retained earnings of $403,000 and $1.8 million,
respectively, as well as decreases in unearned employee stock ownership plan
shares of $498,000. The decrease to accumulated other comprehensive income was
a result of the market value adjustment to the Company's investment securities
available for sale portfolio.  Average stockholders' equity to average assets
was 7.03%, and book value per share was $8.31 at June 30, 2004 compared to
7.22% and $8.98 at December 31, 2003.
