CITIZENS HOLDING COMPANY REPORTS EARNINGS

PHILADELPHIA, Miss.—(BUSINESS WIRE)—April 20, 2017—Citizens Holding Company (NASDAQ:CIZN) announced today results of operations for the three months ended March 31, 2017.

Net income for the three months ended March 31, 2017 was $1.437 million, or $0.29 per share-basic and diluted, down from $1.526 million, or $0.31 per share-basic and diluted for the same quarter in 2016. Net interest income for the first quarter of 2017, after the provision for loan losses, was $6.813 million, approximately 0.9% higher than the same period in 2016. The provision for loan losses for the three months ended March 31, 2017 was negative $151 thousand compared to $60 thousand for the same period in 2016. 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 a decrease in total loans outstanding. The net interest margin decreased to 3.03% in the first quarter of 2017 from 3.12% in the same period in 2016 primarily because of the decrease in yields on earning assets coupled with a small increase in rates paid on interest bearing deposits.

Non-interest income increased in the first quarter of 2017 by $118 thousand, or 6.5%, while non-interest expenses increased $464 thousand, or 7.0%, compared to the same period in 2016. The increase in other non-interest income was mainly the result of an increase in service charges on checking accounts and other service charges and fees. Non-interest expense increased due to an increase in salary and benefit expense of $262 thousand and an increase in other operating expenses of $221 thousand partially offset by a $19 thousand decrease in occupancy expense. The increase in other operating expense was due mainly to repair and maintenance costs for one parcel of other real estate.

Total assets as of March 31, 2017 increased to $1.048 billion, up $22.795 million, or 2.2%, when compared to December 31, 2016. Deposits increased by $29.060 million, or 3.8%, and loans, net of unearned income, decreased by $1.166 million, or 0.3%, when compared to December 31, 2016. The decrease in loans, net of unearned income, was due to payments on loans in excess of current loan demand. Non-performing assets decreased by $128 thousand to $13.400 million at March 31, 2017 as compared to $13.528 million at December 31, 2016, because of decreases in other real estate owned and in loans 90 days or more past due and still accruing interest offset by an increase in non-accrual loans.

During the three months of 2017, the Company paid dividends totaling $0.24 per share.
