ESSA BANCORP, INC. ANNOUNCES OPERATING RESULTS

FOR THE SECOND FISCAL QUARTER OF 2010

Stroudsburg, Pennsylvania, April 28, 2010 — ESSA Bancorp, Inc. (the “Company”) (NASDAQ Global Market^SM “ESSA”) the holding company for ESSA Bank & Trust (the “Bank”) today announced its operating results for the three and six months ended March 31, 2010. The Company reported net income of $1.6 million, or $0.12 per diluted share, for the three months ended March 31, 2010, as compared to net income of $1.5 million, or $0.11 per diluted share, for the corresponding 2009 period. For the six months ended March 31, 2010, the Company reported net income of $2.4 million or $0.18 per diluted share, as compared to net income of $3.4 million or $0.24 per diluted share for the corresponding 2009 period.

Net income of $2.4 million for the six months ending March 31, 2010, included a pre-tax write-down of $1.2 million in the value of the Company’s foreclosed real estate portfolio. The charge related to a single property in the Bank’s foreclosed real estate portfolio and was made during the first fiscal quarter of 2010 to reflect an updated appraisal. Net income for the six months ended March 31, 2009, included a one-time tax benefit of $317,000 which was made during the first fiscal quarter of 2009. This benefit was related to the Company’s other than temporary impairment charge taken in the fourth fiscal quarter of 2008.

“The economy in our market area has changed little since our last quarterly report,” commented Gary S. Olson, President and Chief Executive Officer of the Company. “Persistent unemployment remains a key deterrent to a local turnaround. It is the primary reason our loan loss provision increased from quarter to quarter. Overall, the Company

has achieved positive results. Most noteworthy, our earnings for the quarter were strong, deposits grew at an unprecedented rate, and we opened three new branches. Our capital position remains rock solid and our credit quality remains well above industry norms.”

Net Interest Income:

Net interest income decreased $5,000, or 0.1%, to $7.2 million for the three months ended March 31, 2010, compared to the same period in 2009. The decrease was primarily attributable to a decrease in the Company’s average net earning assets of $11.1 million, offset in part by an increase in the Company’s interest rate spread to 2.50% for the three months ended March 31, 2010, from 2.39% for the comparable period in 2009.

Net interest income increased $284,000, or 2.0%, to $14.5 million for the six months ended March 31, 2010, from $14.2 million for the comparable period in 2009. The increase was primarily attributable to an increase in the Company’s interest rate spread to 2.48% for the six months ended March 31, 2010, from 2.33% for the comparable period in 2009, offset in part by a decrease of $9.1 million in the Company’s average net earning assets.

Provision for Loan Losses and Net Charge-Offs:

The provision for loan losses increased $275,000, or 73.3%, to $650,000 for the three months ended March 31, 2010, from $375,000 for the comparable period in 2009. The provision for loan losses increased $400,000, or 53.3%, to $1.2 million for the six months ended March 31, 2010, from $750,000 for the comparable period in 2009. Net charge-offs increased $260,000 for the three months ended March 31, 2010 to $259,000 compared to the three-month period ended March 31, 2009 which showed a net recovery of $1,000. Net charge-offs decreased $115,000 for the six months ended March 31, 2010 to $370,000 compared to the same period in 2009.

In evaluating the level of the allowance for loan losses, management considers historical loss experience, the types of loans and the amount of loans in the loan portfolio, adverse situations that may affect a borrower’s ability to repay, the estimated value of any

2

underlying collateral, peer group information, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are subject to interpretation and revision as more information becomes available or as future events occur. The increases in the provision for loan losses for both the three- and six-month periods ended March 31, 2010, as compared to the comparable 2009 periods were in response to this evaluation.

Noninterest Income:

Noninterest income increased $345,000, or 27.3%, to $1.6 million for the three months ended March 31, 2010, from $1.3 million for the comparable period in 2009. The primary reason for the increase was a gain on the sale of investment securities of $308,000 during the 2010 period. The Company sold $13.7 million of adjustable rate investment securities during the three months ended March 31, 2010, as part of a strategy to minimize the impact of the current low interest rate environment.

Noninterest income increased $476,000, or 18.4%, to $3.1 million for the six months ended March 31, 2010, from $2.6 million for the comparable period in 2009. The primary reasons for the increase were gains on sales of investment securities of $308,000 and gains on sales of loans of $195,000. In addition to the sale of $13.7 million in investment securities, the Company sold $8.2 million of long-term fixed rate mortgages during the six months ended March 31, 2010, as part of an overall interest rate risk management strategy.

Noninterest Expense:

Noninterest expense increased $146,000, or 2.5%, to $6.0 million for the three months ended March 31, 2010, from $5.9 million for the comparable period in 2009. The primary reasons for the increase were increases in FDIC insurance premiums of $66,000 and other expenses of $44,000.

Noninterest expense increased $1.6 million, or 13.8%, to $13.3 million for the six months ended March 31, 2010, from $11.7 million for the comparable period in 2009. The primary reasons for the increase were the write-down of foreclosed real estate of $1.2 million in the 2010 period, along with increases in FDIC insurance of $396,000 and

3

compensation and employee benefits of $163,000. These increases were offset, in part, by decreases in occupancy and equipment expense of $142,000 and advertising expense of $88,000.

Balance Sheet:

Total assets increased $16.6 million, or 1.6%, to $1,058.7 million at March 31, 2010, compared to $1,042.1 million at September 30, 2009. The primary reasons for the increase in assets were increases in interest-bearing deposits with other institutions of $8.0 million, investment securities available for sale of $5.4 million, and investment securities held to maturity of $8.5 million. These increases were partially offset by a decrease in net loans receivable of $4.8 million. The Company sold $8.2 million of long-term fixed rate residential loans during the six months ended March 31, 2010, as part of an overall interest rate risk management strategy.

Total deposits increased $73.7 million at March 31, 2010, compared to September 30, 2009, primarily as a result of an increase in certificates of deposit accounts of $55.4 million which included an increase of $36.5 million in brokered certificates of deposit and an increase of $19.0 million in traditional certificates of deposit. These increases were supplemented by an increase in noninterest-bearing demand accounts of $2.3 million, NOW accounts of $2.8 million, money market accounts of $9.0 million, and savings and club accounts of $4.3 million. Borrowed funds decreased during the same time period by $52.8 million primarily because brokered certificates of deposits were a less expensive funding source and because of the other deposit increases noted above.

Stockholders’ equity decreased $6.4 million to $179.1 million at March 31, 2010, compared to $185.5 million at September 30, 2009, primarily as a result of a previously announced stock repurchase program the Company began in June 2008. In June 2009, the Company announced that it had completed its first stock repurchase program having purchased 2,547,135 shares at a weighted average cost of $13.14. It was also announced that the Company’s Board of Directors authorized a second stock repurchase program to purchase up to an additional 10% of its outstanding shares. As of March 31, 2010, the Company had purchased an additional 754,529 shares at a weighted average cost of $12.59 per share under the second stock repurchase program including the repurchase of 359,229 shares at an average cost of $12.38 during the three months ended March 31, 2010.

Asset Quality:

Nonperforming assets totaled $11.9 million, or 1.12%, of total assets at March 31, 2010, compared to $7.7 million, or 0.74%, of total assets at September 30, 2009. The increase was due to increases of $3.2 million in nonperforming residential loans and $2.0 million in commercial loans offset, in part, by a decrease of $779,000 in foreclosed real estate. Commercial nonperforming loans increased primarily as a result of the addition of two commercial real estate relationships in the quarter ended December 31, 2009. Foreclosed real estate declined primarily as a result of the write-down of $1.2 million in the value of one property in the quarter ended December 31, 2009. The Company, in response to these and other trends, made a provision for loan losses of $1.2 million for the six months ended March 31, 2010, compared to a provision of $750,000 for the comparable six-month period in 2009. The allowance for loan losses was $6.6 million, or 0.90%, of loans outstanding at March 31, 2010, compared to $5.8 million, or 0.79%, of loans outstanding at September 30, 2009.
