HERITAGE NOLA BANCORP ANNOUNCES FINANCIAL RESULTS

FOR THE YEAR ENDED DECEMEBER 31, 2018

Covington, Louisiana, February 15, 2019: Heritage NOLA Bancorp, Inc. (the “Company”) (OTC Pink Marketplace – “HRGG”), the holding company of Heritage Bank of St. Tammany (the “Bank”), announces net income of $418,000, or $0.27 per basic and diluted share, for the year ended December 31, 2018, compared to net income of $549,000, or $0.36 per basic and diluted share, for the year ended December 31, 2017. The decrease in net income is primarily attributable to an increase of $785,000 in noninterest expense, partially offset by an increase of $397,000 in net interest income and a decrease of $166,000 in income tax expense. The increase in noninterest expense is primarily attributable to an increase in compensation expenses due to new hires and the implementation of an equity incentive plan. The increase in net interest income is the result of an increase of $8.7 million in average net loans. The Company has continued its growth in net loans by augmenting the portfolio with purchases of loans and loan participations. The decrease in income tax expense reflects the lower effective federal income tax rate in 2018 due to the enactment of the Tax Cuts and Jobs Act of 2017.

Total assets were $119.4 million at December 31, 2018, compared to $110.0 million at December 31, 2017, an increase of $9.4 million. Total loans increased $10.4 million to $100.3 million at December 31, 2018, from $89.9 million at December 31, 2017. Total commercial real estate loans increased $5.5 million to $21.9 million at December 31, 2018 from $16.4 million at December 31, 2017.

Total deposits increased $6.7 million to $77.3 million at December 31, 2018 from $70.6 million at December 31, 2017. Borrowings increased $2.7 million to $16.8 million at December 31, 2018 from $14.1 million at December 31, 2017. Both increases were to help fund loan growth.

Stockholders’ equity remained relatively unchanged at $24 million. Earnings of $418,000 were offset by a decrease in additional paid-in capital of $487,000 as a result of stock repurchases. The Bank remains well-capitalized with ratios well in excess of regulatory minimums.
