ESSA Bancorp, Inc. Announces Fiscal 2020 Fourth Quarter and Full Year Financial Results

Stroudsburg, PA. – October 28, 2020 — ESSA Bancorp, Inc. (the “Company”) (NASDAQ:ESSA), the holding company for ESSA Bank & Trust (the “Bank”), a $1.9 billion asset financial institution providing full service commercial and retail banking, financial, and investment services in eastern Pennsylvania, today announced financial results for the three and twelve months ended September 30, 2020.

Net income was $3.8 million, or $0.38 per diluted share, for the three months ended September 30, 2020, up 3% compared with $3.7 million, or $0.35 per diluted share, for the three months ended September 30, 2019. Net income for the twelve months ended September 30, 2020 was $14.4 million, or $1.39 per diluted share, a 14% increase compared with $12.6 million, or $1.18 per diluted share, for the twelve months ended September 30, 2019.

Gary S. Olson, President and CEO, commented: “The Company’s earnings in the fiscal fourth quarter and full year reflect accomplishments by the entire ESSA team to address challenges in a changing and uncertain environment, while creating opportunities to increase efficiencies and generate significant year-over-year noninterest income growth. Our financial performance enabled us to continue the trend of creating value for shareholders, reflected by higher tangible book value per share, and the continued payment of a quarterly per-share cash dividend.

“Our net interest income increased for the quarter and full year periods compared to the same periods in the prior year. In this very low interest rate environment, our cost of funds decreased faster than the yield on our interest earning assets. Net interest income also reflects the positive impact from a balance sheet deleveraging strategy that the Company executed during the fourth quarter of 2020.”

“We were particularly pleased with the improvement in noninterest income, which in both the quarter and annual fiscal 2020 periods, increased sharply from a year earlier. The primarily drivers of the increase were fee income from commercial loan swaps, gain on the sale of investment securities and income from the sale of long-term, fixed-rate mortgages into the secondary market.

“Residential housing activity has been brisk in our markets, particularly in the Poconos, which has had an increased number of home sales and median home pricing growth not seen in many years. This may partially reflect some national trends of more people expecting to permanently work from home and moving from major urban areas. We also remain busy as a commercially focused financial institution as we continue our longstanding commitment to grow commercial loans as a percentage of total loans. Even with continued physical restrictions at our branches, the number of transactions processed has remained consistently high and our deposit balances have grown. Overall, we continue to maintain high levels of service and operations while ensuring the health and safety of our employees and customers.

“The Company’s portfolio of commercial and residential mortgage loans demonstrated overall sound quality, and there were relatively few requests for payment relief in the fiscal fourth quarter of 2020. We continue to monitor credit quality across our entire loan portfolio. Borrowers requesting payment relief, which amounted to 12.4% of our total loans outstanding at June 30, 2020 declined significantly, to 4.5% of total loans outstanding at September 30, 2020. Loans still in forbearance at September 30, 2020 included $56.2 million in commercial real estate, $2.1 million in commercial, $5.0 million in mortgage and $179,000 in auto. We continued to conservatively reserve for loan losses to reflect ongoing economic uncertainty and are diligently monitoring credit and have increased communications with customers to proactively address potential problems.

“As we enter a new fiscal year, we believe the Company is well positioned to maintain strong capital, liquidity and credit quality, risks that we have focused on since the outset of the crisis, to insure that we can continue to perform well in these challenging and changing economic times.”

SELECTED FINANCIAL HIGHLIGHTS

Fiscal Fourth Quarter, Twelve Months 2020 Income Statement Review

Total interest income was $15.4 million for the three months ended September 30, 2020 compared with $16.8 million for the three months ended September 30, 2019 reflecting a decline in interest rates and, therefore, a decrease in the total yield on average interest earning assets from 3.92% for the quarter ended September 30, 2019 to 3.25% for the quarter ended September 30, 2020. The decline in rates was partially offset by growth of $175.1 million in average interest earning assets.

Interest expense was $2.9 million for the quarter ended September 30, 2020 compared to $5.1 million for the same period in 2019. A decline in the cost of funds from 1.44% for the 2019 period to 0.77% for the 2020 period was offset, in part, by growth of $93.2 million in average interest-bearing liabilities. As noted, the Company significantly reduced wholesale interest-bearing liabilities in the fiscal fourth quarter of 2020 with its deleverage strategy.

Total interest income was $64.1 million for the twelve months ended September 30, 2020 compared with $67.8 million for the twelve months ended September 30, 2019. Interest expense was $15.9 million for the twelve months ended September 30, 2020 compared with $20.7 million for the same period in 2019. A decline in the total yield on average interest earning assets from 3.93% for the year to date period ended September 30, 2019 to 3.57% for the same period in 2020 was offset, in part, by growth of $72.2 million in average interest earning assets. A decrease in the cost of funds to 1.08% for the 2020 period from 1.43% for the 2019 period, offset in part, by an increase of $17.7 million in average interest-bearing liabilities, was the primary driver of the decrease in interest expense. Net interest income was $12.4 million for the three months ended September 30, 2020 compared to $11.7 million for the three months ended September 30, 2019. The net interest margin for the fourth quarter of fiscal 2020 was 2.64%, compared with 2.73% for the fourth quarter of fiscal 2019. The net interest rate spread was 2.48% for the fourth quarter of fiscal 2020, compared with 2.48% for the fiscal fourth quarter of 2019.

For the twelve months ended September 30, 2020, net interest income was $48.2 million compared with $47.0 million for the twelve months ended September 30, 2019, reflecting relatively stable income from loans, offset by lower income from investment securities. Total interest expense declined sharply in fiscal 2020 compared with the previous year. The net interest margin for the twelve months of fiscal 2020 was 2.68% compared with 2.73% for the twelve months of fiscal 2019. The net interest rate spread was 2.49% for the twelve months of fiscal 2020, compared with 2.50% for the twelve months of fiscal 2019.

Net interest income after provision for loan losses in the three and twelve months of fiscal 2020 reflected a higher provision for loan losses, primarily reflecting prudent reserving practices in light of economic conditions and uncertainties. The Company’s provision for loan losses was $1.1 million for the three months ended September 30, 2020, compared with $200,000 for the three months ended September 30, 2019. The Company’s provision for loan losses was $3.3 million for the twelve months ended September 30, 2020 compared with $2.1 million for the twelve months ended September 30, 2019.

Noninterest income increased $3.1 million or 149% to $5.2 million for the three months ended September 30, 2020, compared with $2.1 million for the three months ended September 30, 2019. The Company’s deleverage transaction contributed $2.5 million to the increase in noninterest income. Net of this gain, the increase for the quarter was $593,000 or 28.2%. Noninterest income in the fiscal fourth quarter of 2020 included approximately $676,000 in gains on sales of residential mortgages, primarily 30-year fixed rate loans. Loan swap fees were $94,000 in fiscal fourth quarter 2020 compared to no similar fees in fiscal fourth quarter 2019.

For the twelve months ended September 30, 2020, noninterest income was $13.3 million compared with $8.2 million for the twelve months ended September 30, 2019. The increase in noninterest income year over year, net of the deleverage gain, was $2.6 million or 31.3%. For the twelve months ended September 30, 2020, gains on the sale of loans and investment securities increased $1.5 million and $2.9 million, respectively. Loan swap fees were $1.3 million for the twelve months ended September 30, 2020, compared to no similar fees in the comparable period in 2019.

Noninterest expense was $11.9 million for the three months ended September 30, 2020 compared with $9.2 million for the comparable period a year earlier. Net of the prepayment penalty, noninterest expense was $9.4 million for the three months ended September 30, 2020. Noninterest expense was $40.6 million for the twelve months ended September 30, 2020 compared with $38.1 million for the comparable period a year earlier. Net of the prepayment penalty, noninterest expense was $38.1 million for the twelve months ended September 30, 2020.

Balance Sheet, Asset Quality and Capital Adequacy Review

Total assets increased $94.1 million to $1.89 billion at September 30, 2020, from $1.80 billion at September 30, 2019, primarily due to increases in cash and cash equivalents and loans receivable, offset in part by a decline in investment securities available for sale.

Cash and cash equivalents increased $103.7 million during the first twelve months of fiscal 2020 as a result of the previously discussed pandemic-driven balance sheet adjustments made to grow cash to mitigate potential liquidity risks. At September 30, 2020 cash and cash equivalents were $155.9 million compared with $52.2 million at September 30, 2019. The Company built the majority of its cash position in the fiscal second quarter of 2020 through increased longer-term borrowings at attractive rates and has maintained that position throughout the remainder of fiscal 2020.

Total net loans increased to $1.42 billion at September 30, 2020 from $1.33 billion at September 30, 2019, reflecting growth in residential mortgages, construction loans and both commercial real estate and commercial and industrial loans. Residential real estate loans were $610.4 million at September 30, 2020, up $12.9 million from September 30, 2019. The Company sold $30.3 million in residential mortgage loans to the Federal Home Loan Bank of Pittsburgh during the fiscal year. Indirect auto loans declined to $39.8 million at September 30, 2020 from $82.0 million at September 30, 2019, reflecting expected runoff of the portfolio following the Company’s previously announced discontinuation of indirect auto lending in July 2018.

Commercial real estate loans were $509.6 million at September 30, 2020, up from $480.6 million at September 30, 2019. Commercial loans (primarily commercial and industrial) increased to $139.6 million at September 30, 2020 from $55.6 million at September 30, 2019 due primarily to PPP loans of $76.8 million.

Total deposits were $1.54 billion at September 30, 2020 up 15.0% compared with $1.34 billion at September 30, 2019. Core deposits (demand accounts, savings and money market) were $1.08 billion, or 70% of total deposits, at September 30, 2020 compared to $900.3 million, or 67.04% of total deposits, at September 30,

2019. Noninterest bearing demand accounts exhibited strong year-over-year growth, increasing 38% to $242.6 million, interest bearing demand accounts grew 22% to $274.7 million and money market accounts grew 10% to $401.9 million. Total borrowings decreased $122.4 million to $125.9 million at September 30, 2020 from $248.3 million at September 30, 2019 primarily as a result of the deleverage transaction discussed earlier.

Nonperforming assets totaled $20.6 million, or 1.09% of total assets, at September 30, 2020, up from $10.3 million, or 0.57% of total assets, at September 30, 2019. The primary reason for the increase in nonperforming assets at September 30, 2020 as compared to September 30, 2019 was the addition of two nonperforming commercial real estate loans totaling $9.3 million. The Company notes these loans are well collateralized and carry personal guarantees.

For the three months ended September 30, 2020, the Company’s return on average assets and return on average equity were 0.76% and 7.77%, compared with 0.82% and 7.72%, respectively, in the comparable period of fiscal 2019. For the twelve months ended September 30, 2020, the Company’s return on average assets and return on average equity were 0.76% and 7.43%, compared with 0.69% and 6.80%, respectively, in the comparable period of fiscal 2019.

The Bank continued to demonstrate financial strength with a Tier 1 leverage ratio of 9.08% at September 30, 2020, exceeding regulatory standards for a well-capitalized institution.

Total stockholders’ equity increased $1.9 million to $191.4 million at September 30, 2020, from $189.5 million at September 30, 2019, primarily reflecting net income growth, offset in part by a decline in comprehensive income, dividends paid to shareholders and changes in treasury stock. Tangible book value per share at September 30, 2020 was $16.26, compared with $15.43 at September 30, 2019.
