CITIZENS HOLDING COMPANY REPORTS EARNINGS

PHILADELPHIA, Miss.—(BUSINESS WIRE)—January 28, 2020—Citizens Holding Company (NASDAQ:CIZN) announced today results of operations for the three and twelve months ended December 31, 2019.

Net income for the three months ended December 31, 2019 was $1.971 million, or $0.35 per share-basic and diluted, an increase of $256 thousand from net income of $1.715 million, or $0.35 per share-basic and diluted for the same quarter in 2018. The majority of the increase relates to an increase in the net interest income partially offset by an increase in income tax expense.

Net interest income for the fourth quarter of 2019, after the provision for loan losses, was $7.204 million, approximately 15.6% higher than the same period in 2018. The provision for loan losses for the three months ended December 31, 2019 was $101 thousand compared to $193 thousand for the same period in 2018. The decrease in the provision reflects management’s estimate of inherent losses in the loan portfolio including the impact of current local and national economic conditions and minimal loan losses in recent years. The net interest margin was 2.79% for the fourth quarter of 2019 compared to 2.93% for the same period in 2018. This decrease was due to an increase in interest rates paid on interest bearing liabilities partially offset by an increase in yields on interest bearing assets.

Non-interest income increased in the fourth quarter of 2019 by $922 thousand, or 41.9%, while non-interest expenses increased $952 thousand, or 14.1%, compared to the same period in 2018. The increase in non-interest income was mainly the result of gains from security sales due to strategic investment decisions coupled with death benefit proceeds from a bank-owned life insurance policy partially offset by a decrease in mortgage loan origination income. Non-interest expense increased primarily due to an increase in salaries and benefits from the Charter Bank acquisition coupled with acquisition-related professional fees.

Net income for the twelve months ended December 31, 2019 decreased 11.5% to $5.902 million, or $1.17 per share-basic and diluted, from $6.672 million, or $1.36 per share-basic and diluted, for the twelve months ended December 31, 2018.

Net interest income for the twelve months ended December 31, 2019, after the provision for loan losses, decreased 5.6% to $25.066 million from $26.566 million for the year ended in 2018. Net interest margin for the twelve months ended December 31, 2019, decreased to 2.77% in 2019 from 3.05% in 2018. The provision for loan losses for the twelve months ended December 31, 2019 was $573 thousand compared to $334 thousand in 2018.

Non-interest income increased by $1.149 million, or 13.3%, and non-interest expense decreased by $107 thousand, or 0.4%, for the twelve months ended December 31, 2019 when compared to the same period in 2018. The increase in non-interest income was discussed above. The decrease in non-interest expense was mainly due to a refund of excess prepaid postage and continued cost containment focus throughout the Company, partially offset by an increase in salaries and benefits related to the Charter Bank acquisition.

Total assets as of December 31, 2019 increased to $1.195 billion, up $236.804 million, or 24.7%, when compared to $958.630 million at December 31, 2018. Deposits increased by $142.774 million, or 18.9%, and loans, net of unearned income, increased by $147.790 million, or 34.4%, when compared to December 31, 2018. The increase in loans, net of unearned income, was due

to the Charter Bank acquisition coupled with new loan demand in excess of loan paydowns. Non-performing assets increased by $2.454 million to $15.802 million at December 31, 2019 as compared to $13.348 million at December 31, 2018, due to an increase in non-accrual loans and loans 90 days or more past due and still accruing and other real estate owned.

During the twelve months ended December 31, 2019, the Company paid dividends totaling $0.96 per share.
