ESSA Bancorp, Inc. Announces Fiscal 2019

Third Quarter, Nine Month Financial Results

Stroudsburg, PA. – July 24, 2019 — ESSA Bancorp, Inc. (the “Company”) (NASDAQ:ESSA), the holding company for ESSA Bank & Trust (the “Bank”), a $1.8 billion asset financial institution providing full service retail and commercial banking, financial, and investment services in eastern Pennsylvania, today announced financial results for the three months and nine months ended June 30, 2019.

Net income was $3.0 million, or $0.29 per diluted share, for the three months ended June 30, 2019, compared with $2.8 million, or $0.26 per diluted share, for the three months ended June 30, 2018. Net income was $8.9 million, or $0.83 per diluted share, for the nine months ended June 30, 2019, compared with $3.4 million or $0.32 per diluted share, for the nine months ended June 30, 2018. Results for the nine months ended June 30, 2018 reflect a one-time charge to income tax expense of $3.7 million recorded in the Company’s first fiscal quarter of 2018 related to the reduction in the carrying value of the Company’s deferred tax assets, which resulted from the reduction in the federal corporate income tax rate under the Tax Cuts and Jobs Act of 2017.

Gary S. Olson, President and CEO, commented: “Year-over-year earnings growth, improved return on average assets and average equity, and increased shareholder value reflected the Company’s focus on growing our commercial lending and banking business, maintaining our historical strength in residential mortgage and municipal lending, and maintaining overall asset quality. Generating cost-effective funding for our accelerating loan activity has been a key goal for ESSA, and we were pleased that continued growth in core deposits and use of internal funding sources has led to a significant decrease in short-term borrowings to support lending.

“Operational and systems initiatives to increase productivity have led to consistent year-over-year operating cost reductions as we have progressed through 2019. While focused on efficient operation, we recognize the importance of investing in people and assets that support growth. Our new and expanded Allentown office, relocation to a new, upgraded branch facility in Nazareth, and adding top-performing bankers in our suburban Philadelphia office are examples of our commitment to efficient growth and enhanced productivity.”

FISCAL THIRD QUARTER, NINE MONTHS 2019 HIGHLIGHTS

• Increased earnings reflected the Company’s continuing progress in driving revenue from lending activity, with net income in the fiscal third quarter of 2019 of $3.0 million, up 8.0% from $2.8 million in the fiscal third quarter of 2018. In the first nine months of fiscal 2019, pre-tax income of $10.6 million rose 24.1% compared with the first nine months of fiscal 2018. Pre-tax income provides a better comparison due to the one-time charge to income tax expense of $3.7 million in the fiscal first nine months of 2018 as described above.

• Total interest income increased to $17.0 million in the third quarter of fiscal 2019 from $16.7 million in the third quarter of fiscal 2018, primarily reflecting higher interest income generated by loans.

• Total net loans at June 30, 2019 increased $21.6 million to $1.3 billion from September 30, 2018, primarily reflecting growth in commercial and commercial real estate loans. Year-to-date, net loan growth of $21.6 million includes a decline of $49.8 million in indirect auto loan balances during the same period. Net loans at June 30, 2019 were up 1.9%, or $25.0 million, compared with net loans at June 30, 2018, primarily reflecting commercial loan growth. The year-over-year decline in indirect auto loan balances outstanding was $68.0 million. The Company discontinued indirect auto lending in July 2018.

• Core deposits (demand accounts, savings and money market) increased to 62.9% of total deposits at June 30, 2019 from 58.6% at June 30, 2018, reflecting year-over-year growth in noninterest bearing, lower-cost interest bearing and money market deposits.

• Nonperforming assets totaled $19.1 million, or 1.06% of total assets, at June 30, 2019, up from $11.7 million, or 0.64% of total assets, at September 30, 2018. The increase in nonperforming assets is due to the addition of one commercial loan relationship totaling $8.3 million. It required no addition to the Company’s loan loss provision, as management believes that the Company is well secured and does not expect to incur any principal loss on this credit, which was part of a complex participation loan with other financial institutions.

• Expense management led to a 6.4% decline in total noninterest expense for the quarter ended June 30, 2019 compared to the same period in 2018. Year to date, total noninterest expense declined by 5.1% and the efficiency ratio improved to 69.6% in 2019 from 70.2% in 2018.

• For the three months ended June 30, 2019, the Company’s return on average assets and return on average equity were 0.67% and 6.59%, compared with 0.62% and 6.33%, respectively, in the comparable period of fiscal 2018. The Company’s return on average assets for the nine months ended June 30, 2019 was 0.65% and the return on average equity was 6.48% compared to 0.25% and 2.55% for the same period in fiscal 2018. Total stockholders’ equity increased to $188.1 million at June 30, 2019 from $179.2 million at September 30, 2018. Tangible book value per share at June 30, 2019 increased to $15.17, compared with $13.92 at September 30, 2018.

• The Company paid a quarterly cash dividend of $0.10 per share on June 28, 2019, its 45^th consecutive quarterly cash dividend to shareholders.

Fiscal Third Quarter, Nine Months Income Statement Review

Total interest income was $17.0 million for the three months ended June 30, 2019, up from $16.7 million for the three months ended June 30, 2018. The primary driver was growth in interest income from loans to $14.3 million in fiscal second quarter 2019, up from $14.0 million a year earlier. Interest expense was $5.3 million for the quarter ended June 30, 2019 compared to $4.2 million for the same period in 2018, partially reflecting growth in deposits along with increases in the cost of both borrowings and retail deposits.

Total interest income was $51.0 million for the nine months ended June 30, 2019, up 6.4% from $47.9 million for the nine months ended June 30, 2018. The primary driver was 6.4% growth in interest income from loans to $42.2 million in 2019, up from $39.7 million in the same period a year earlier. Interest expense in the first half of fiscal 2019 was $15.7 million compared to $11.7 million for the same period in 2018.

Net interest income was $11.7 million for the three months ended June 30, 2019, compared with $12.6 million for the comparable period in fiscal 2018. The net interest margin for the third quarter of fiscal 2019 was 2.74%, compared with 2.98% for the third quarter of fiscal 2018. The net interest rate spread was 2.49% in third quarter fiscal 2019, compared with 2.84% for the third quarter of fiscal 2018.

For the nine months ended June 30, 2019, net interest income was $35.3 million compared with $36.3 million for the comparable period in 2018. The net interest margin for the nine months ended June 30, 2019 was 2.72%, compared with 2.87% for the same period in 2018. The net interest rate spread was 2.51% in nine months ended June 30, 2019, compared with 2.75% for 2018.

The Company’s provision for loan losses decreased to $400,000 for the three months ended June 30, 2019, compared with $975,000 for the three months ended June 30, 2018. This decrease reflected provisioning primarily related to declining charge off activity. The Company’s provision for loan losses decreased to $1.9 million for the nine months ended June 30, 2019, compared with $3.1 million for the nine months ended June 30, 2018.

Noninterest income remained at $1.9 million for the three months ended June 30, 2019, compared with the three months ended June 30, 2018.

For the nine months ended June 30, 2019, noninterest income increased 4.2% to $6.1 million compared with $5.8 million for the nine months ended June 30, 2018. An increase in other income was the primary driver of the noninterest income increase, which included the recovery of $226,000 of previously expensed professional fees related to the settlement of a non-performing loan and the settlement of approximately $280,000 from a previously purchased credit impaired loan.

Noninterest expense decreased to $9.5 million for the three months ended June 30, 2019 compared with $10.2 million for the comparable period in fiscal 2018. Noninterest expense decreased $1.6 million or 5.1%, to $28.9 million for the nine months ended June 30, 2019 compared with $30.4 million for the comparable period in fiscal 2018. All noninterest expense categories other than compensation and employee benefits and data processing for the nine months ended June 30, 2019 decreased compared to the same period in 2018 reflecting the Company’s focus on expense management and reducing its efficiency ratio.

Balance Sheet, Asset Quality and Capital Adequacy Review

Total assets decreased $33.8 million to $1.80 billion at June 30, 2019, from $1.83 billion at September 30, 2018, primarily due to a decline in investment securities available for sale, offset in part by growth in loans.

Total net loans increased to $1.33 billion at June 30, 2019 from $1.31 billion at September 30, 2018. Residential real estate loans were $595.8 million at June 30, 2019, up $15.2 million from September 30, 2018. The Company purchased $22.3 million of 1 to 4 family, adjustable-rate residential loans during the quarter ended December 31, 2018. Indirect auto loans declined $49.8 million to $96.4 million at June 30, 2019 from $146.2 million at September 30, 2018, reflecting expected runoff of the portfolio following our previously announced discontinuation of indirect auto lending in July 2018.

Commercial real estate (“CRE”) loans were $462.8 million at June 30, 2019, up from $416.6 million at September 30, 2018 and reflected strong year-over-year growth from $396.8 million at June 30, 2018. Residential multi-family lending has been a particularly strong component of CRE activity. Commercial (primarily commercial and industrial) loans increased to $58.7 million at June 30, 2019 from $49.5 million at September 30, 2018 and were up from $49.6 million at June 30, 2018, reflecting balanced activity in a number of business sectors.

Total deposits decreased $5.3 million, or 0.4%, to $1.33 billion at June 30, 2019 from September 30, 2018. Core deposits (demand accounts, savings and money market) were $837.1 million, or 62.9% of total deposits, at June 30, 2019 compared to $743.5 million, or 58.6% of total deposits, at June 30, 2018. Noninterest bearing demand accounts exhibited strong year-over-year growth, increasing 7.0% to $176.4 million, while interest bearing demand accounts grew 7.6% to $182.3 million. Total borrowings decreased $44.5 million to $254.0 million at June 30, 2019 from $298.5 million at September 30, 2018.

Nonperforming assets totaled $19.1 million, or 1.06% of total assets, at June 30, 2019, up from $11.7 million, or 0.64% of total assets, at September 30, 2018. As previously stated, the increase in nonperforming assets is due to the addition of one commercial loan relationship totaling $8.3 million. The allowance for loan losses was $12.6 million, or 0.94% of loans outstanding, at June 30, 2019, up from $11.7 million, or 0.89% of loans outstanding at September 30, 2018, primarily reflecting prudent reserving to match commercial loan growth.

For the three months ended June 30, 2019, the Company’s return on average assets and return on average equity were 0.67% and 6.59%, compared with 0.62% and 6.33%, respectively, in the comparable period of fiscal 2018. For the nine months ended June 30, 2019, the Company’s return on average assets and return on average equity were 0.65% and 6.48%, compared with 0.25% and 2.55%, respectively for the comparable fiscal 2018 period.

The Bank continued to demonstrate financial strength with a Tier 1 leverage ratio of 9.33% at June 30, 2019, exceeding regulatory standards for a well-capitalized institution. The Company maintained a tangible equity to tangible assets ratio of 9.27% at June 30, 2019.

Total stockholders’ equity increased $8.9 million to $188.1 million at June 30, 2019, from $179.2 million at September 30, 2018, primarily reflecting increases from net income and the change in other comprehensive loss, offset in part by dividends paid to shareholders and a $6.5 million stock buyback. Tangible book value per share at June 30, 2019 was $15.17, compared with $13.92 at September 30, 2018.
