                 ESSA BANCORP, INC. ANNOUNCES OPERATING RESULTS
                     FOR THE SECOND FISCAL QUARTER OF 2008



Stroudsburg,  Pennsylvania, April 24, 2008 -- ESSA Bancorp, Inc. (the "Company")
(NASDAQ:  "ESSA") the holding  company for ESSA Bank & Trust (the "Bank")  today
announced  its  operating  results for the three and six months  ended March 31,
2008. The Company  reported net income of $1.7 million,  or $0.11 per share, for
the three months ended March 31, 2008, as compared to net income of $1.3 million
for the corresponding  2007 period.  The Company's net average  interest-earning
assets for the three months ended March 31, 2008 increased  $124.4  million,  or
155.8%, as compared to net average  interest-earning assets for the three months
ended March 31, 2007. The increase was the result of a $74.3 million increase in
average loans  outstanding  as compared to the  comparable  period in 2007 along
with  a  combined   increase  of  $106.9  million  in  average   investment  and
mortgage-backed  securities as compared to the  comparable  period in 2007.  The
securities  increased  primarily due to the  investment of the net proceeds from
the Bank's mutual-to-stock conversion and the Company's stock offering.

For the six months ended March 31, 2008, the Company reported net income of $3.4
million,  or $0.21 per share,  as compared to net income of $2.2 million for the
comparable  period in 2007.  The primary  reasons for the increase in net income
for  the six  month  period  are  the  same as  those  described  above  for the
three-month  increase.  Net average  earning assets  increased  $135.9  million,
average loans  outstanding  increased $71.6 million and average  investments and
mortgage-backed  securities  increased  $110.5  million for the six months ended
March 31, 2008, as compared to the comparable period in 2007.




"We are pleased to report a solid second quarter," said Gary S. Olson, President
and Chief  Executive  Officer of the  Company.  "Our  results  are  particularly
gratifying in light of the difficult  interest rate and competitive  environment
financial  institutions  are  operating in at this time. We continue to focus on
the growth of our loan portfolio, which grew over 3.4 percent during the quarter
and 6.6 percent  since the  beginning of our fiscal year.  At the same time,  we
continue to avoid subprime  loans and other high risk assets.  Our asset quality
remains strong as evidenced by our low ratio of  non-performing  assets to total
assets."

The Bank underwent a  mutual-to-stock  conversion as part of the Company's stock
offering that was  consummated on April 3, 2007. The stock offering  resulted in
gross  proceeds of $158.7  million  through the sale of  15,870,000  shares at a
price of $10.00 per  share.  The  Company  contributed  1,110,900  shares of its
common stock to the ESSA Bank & Trust Foundation (the  "Foundation")  along with
$1.6  million  in cash.  Net  proceeds  from the  stock  offering  prior to this
contribution  to  the  Foundation  were  $155.8  million.  Concurrent  with  the
conversion,  the Company lent approximately $13.6 million to the Bank's Employee
Stock Ownership Plan. The Company  retained  approximately  $64.3 million of the
net proceeds prior to the contribution to the Foundation,  and the remaining net
proceeds were  contributed to the Bank.  The stock  offering  proceeds have been
invested in short-term,  investment-grade  debt obligations and  mortgage-backed
securities  debt  issued  by  United  States  government-sponsored  agencies  or
entities.  Approximately $29.7 million of the net proceeds of the stock offering
were used to pay down short-term debt at the Bank.

Net Interest Income:

Net interest  income  increased $1.5 million,  or 29.5%, to $6.4 million for the
three months ended March 31, 2008,  from $4.9 million for the comparable  period
in 2007. The increase was primarily  attributable to the increase in net average
earning  assets  and was  offset  in part by a 34 basis  point  decrease  in the
Company's  interest  rate spread to 2.00% for the three  months  ended March 31,
2008, from 2.34% for the comparable period in 2007.

                                       2


Net interest income  increased $3.4 million,  or 36.9%, to $12.6 million for the
six months ended March 31, 2008, from $9.2 million for the comparable  period in
2007.  The increase was  primarily  attributable  to the increase in net average
earning  assets  and was  offset  in part by a 30 basis  point  decrease  in the
Company's interest rate spread to 1.97% for the six months ended March 31, 2008,
from 2.27% for the comparable period in 2007.

Non-Interest Income:

Non-interest  income  was  unchanged  in the 2008  period  compared  to the 2007
period,  remaining at $1.3 million for the three months ended March 31, 2008 and
2007, respectively.

Non-interest  income  increased  $63,000,  or 2.3%,  to $2.8 million for the six
months ended March 31,  2008,  from $2.7  million for the  comparable  period in
2007.  Increases in service charges and fees on loans, trust and investment fees
and earnings on bank-owned life insurance were offset,  in part, by decreases in
service fees on deposit accounts, net gain on sale of loans and other income.

Non-Interest Expense:

Non-interest expense increased $889,000, or 20.7%, to $5.2 million for the three
months ended March 31,  2008,  from $4.3  million for the  comparable  period in
2007. The primary  reasons for the increase were increases in  compensation  and
employee benefits of $416,000, occupancy and equipment of $75,000,  professional
fees of $228,000  and other  expenses of  $150,000.  Compensation  and  employee
benefits  increased  primarily as a result of normal  compensation  increases of
$222,000 in addition to an expense of  $129,000  related to the  Employee  Stock
Ownership  Plan which was  implemented  in April 2007.  Occupancy  and equipment
costs  increased  primarily  as a result of increases in rental costs of $30,000
along with  increases  in  depreciation  expense of $17,000.  Professional  fees
increased  primarily as a result of increased  legal,  accounting and regulatory
fees  associated   with  being  a  public   reporting   company,   and  included
approximately  $72,000  related to the Company's  compliance with Section 404 of
the Sarbanes-Oxley  Act. Other expenses increased primarily due to the reversal,
in March 2007, of a $101,000  accrued  expense for  contributions  to the Bank's
former charitable

                                       3


foundation.  Prior to the Bank's mutual-to-stock  conversion,  the Bank had been
setting  aside  approximately  10% of its net  income as a  contribution  to its
charitable  foundation.  This  practice  was  discontinued  in  March  2007,  in
contemplation  of the  Bank's  impending  conversion  and  the  Company's  stock
offering. As described earlier, the Company made a $12.6 million contribution to
a new charitable  foundation in April 2007  concurrent  with the Company's stock
offering.

Non-interest  expense increased $1.5 million, or 17.1%, to $10.2 million for the
six months ended March 31, 2008, from $8.7 million for the comparable  period in
2007. The primary  reasons for the increase were increases in  compensation  and
employee benefits of $838,000, occupancy and equipment of $142,000, professional
fees of $380,000  and other  expenses of  $100,000.  Compensation  and  employee
benefits  increased  primarily as a result of normal  compensation  increases of
$407,000  along with an  expense  of  $300,000  related  to the  Employee  Stock
Ownership  Plan which was  implemented  in April 2007.  Occupancy  and equipment
costs  increased  primarily  as a result of increases in rental costs of $51,000
along with  increases  in  depreciation  expense of $40,000.  Professional  fees
increased  primarily as a result of increased  legal,  accounting and regulatory
fees associated with being a public reporting company,  including  approximately
$144,000   related  to  the  Company's   compliance  with  Section  404  of  the
Sarbanes-Oxley  Act.  Other expense  increased  primarily due to increased  loan
processing costs related to increased volume.



Balance Sheet

Total assets  increased  $57.4 million,  or 6.3%, to $967.8 million at March 31,
2008,  compared to $910.4 million at September 30, 2007. The primary reasons for
the increase in assets were increases in  certificates of deposit and investment
securities  of $13.3  million,  net loans  receivable  of $41.1  million  and an
increase in cash and cash  equivalents  of $2.0  million.  The increase in loans
receivable included increases in residential loans of $31.1 million,  commercial
