ESSA Bancorp, Inc. Announces Fiscal

Second Quarter, First Half 2023 Financial Results

Stroudsburg, PA. – April 26, 2023 — ESSA Bancorp, Inc. (the “Company”) (NASDAQ:ESSA), the holding company for ESSA Bank & Trust (the “Bank”), a $2.0 billion asset financial institution providing full service commercial and retail banking, financial, and investment services in eastern Pennsylvania, today announced financial results for the fiscal second quarter and six months ended March 31, 2023.

Net income was $4.7 million, or $0.48 per diluted share, for the three months ended March 31, 2023 compared with $4.6 million, or $0.47 per diluted share, for the three months ended March 31, 2022. Net income was $9.6 million, or $0.98 per diluted share, for the six months ended March 31, 2023 compared with $9.2 million, or $0.94 per diluted share, for the six months ended March 31, 2022. Other highlights include:

• First half of fiscal 2023 net interest income grew 10.8% year-over-year, primarily reflecting loan growth driving expanded total interest income.

• Total net loans increased 9.3% in the first half of fiscal 2023 and 17.1% year-over- year.

• Growth in commercial real estate loans, including construction, and residential real estate loans, drove the increase in total loans.

• Total deposits increased 3.6% in the first half of fiscal 2023 primarily due to increases in certificates of deposit.

• Core deposits (demand, savings and money market accounts) comprised 77% of total deposits at March 31, 2023 and uninsured deposits, net of fully collateralized municipal deposits, were 17.2% of total deposits.

• Despite continuing economic uncertainties, shareholder value measures rose, including tangible book value and total stockholders’ equity. Tangible book value per share increased to $19.69 at March 31, 2023 from $19.12 at September 30, 2022.

Gary S. Olson, President and CEO, commented: “The Company’s focus on maintaining capital strength, liquidity and stable asset quality supported positive financial performance and growth leading to enhanced shareholder value in the second quarter and first half of 2023. We continued to monitor and address the higher interest rate environment, which has increased the Company’s cost of funds. However, organic loan growth and disciplined rate increases have so far more than offset the cost of funds increases.

“As expected, new loan growth has begun to slow, reflecting the higher interest rate environment for commercial and residential loans plus caution in light of inflation and potential recession concerns. However, we continue to have healthy pipelines for commercial loans, prepayment speeds on loans have slowed, our indirect auto loans runoff is virtually complete so we expect that net loans outstanding will continue to grow.

“Total deposits, which represent our primary source of loan funding, increased, reflecting the growth in higher-interest certificates of deposits. While the level of demand deposits declined, the deposit portfolio reflected normal levels of change and the Company did not experience any unusual or concerning deposit outflows during the recent, highly publicized banking industry turmoil.

“The Company has entered the second half of the fiscal year with a stable base of loans and deposits and a promising outlook for continued financial strength, stability, credit quality, and growth.”

FISCAL SECOND QUARTER 2023 HIGHLIGHTS

• For the three months ended March 31, 2023, the Company’s return on average assets and return on average equity were 0.98% and 8.63%, compared with 1.00% and 8.82%, respectively, for the comparable period of fiscal 2022.

• Asset repricing and loan growth in a rising rate environment contributed to net interest margin increasing to 3.34% for the second quarter of 2023 compared with 3.26% for the comparable period of fiscal 2022 and 3.42% for the first six months of fiscal 2023 compared with 3.15% for the first six months of 2022.

• Unrealized losses due to rising interest rates in the Company’s available for sale investment securities portfolio were offset, in large part, by unrealized gains in the Company’s derivative balance sheet hedges.

Balance Sheet, Asset Quality and Capital Adequacy Review

Total assets were $1.99 billion at March 31, 2023 compared with $1.86 billion at September 30, 2022, respectively. The increase of $123.7 million, or 6.6% primarily reflects the growth in total net loans outstanding.
