ESSA Bancorp, Inc. Announces Fiscal

Third Quarter, Nine Months 2023 Financial Results

Stroudsburg, PA. – July 26, 2023 — ESSA Bancorp, Inc. (the “Company”) (NASDAQ:ESSA), the holding company for ESSA Bank & Trust (the “Bank”), a $2.2 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 third quarter and nine months ended June 30, 2023.

Net income was $4.4 million, or $0.45 per diluted share, for the three months ended June 30, 2023, compared with $5.0 million, or $0.51 per diluted share, for the three months ended June 30, 2022. Net income was $13.9 million, or $1.44 per diluted share, for the nine months ended June 30, 2023, compared with $14.2 million, or $1.46 per diluted share, for the nine months ended June 30, 2022. Highlights include:

Gary S. Olson, President and CEO, commented: “The Company’s financial performance in fiscal 2023 has exceeded expectations. Although net income in the third quarter and nine months was down slightly from the previous year, we feel our performance reflects exceptional resilience and productivity in light of inflationary concerns and rapidly rising interest rates.

“We have experienced steady activity in commercial real estate and commercial construction lending and continue to maintain our pipeline. Higher interest rates have allowed us to portfolio more residential mortgage production resulting in loan growth of 11% since the start of the fiscal year, and up 16% from a year ago. We have accomplished this despite thin housing inventories and higher interest rates.

“Our ability to quickly respond to rising interest rates generated 35% year-over-year growth of total interest income. We believe our value proposition, which includes integrated banking capabilities, digital technology, and the exceptional service we provide to commercial and retail clients, have been key to retaining customers and earning new business.

“Generating strong interest income and managing returns on interest-earning assets has kept us ahead of increased interest expense. Although under pressure, net interest margin and interest spread are sound. We have maintained a diverse range of depositors and a low percentage of uninsured deposits to total deposits, reflecting an emphasis on deposit risk management.

“A commitment to continually improving operational productivity and efficiency reflects a focus on maximizing the value of the company. Strong asset quality, supported by diligent credit management and regular stress testing of our loan portfolios, enables the Company to stay ahead of issues that could potentially impact financial performance.

“Approaching the close of fiscal 2023, we are focused on a strong finish, managing expenses, proactively responding to market and interest rate shifts, and consistently building value for shareholders.”
