CITIZENS HOLDING COMPANY REPORTS EARNINGS

PHILADELPHIA, Miss.—(BUSINESS WIRE)—October 27, 2017—Citizens Holding Company (NASDAQ:CIZN) announced today results of operations for the three and nine months ended September 30, 2017.

Net income for the three months ended September 30, 2017 was $1.608 million, or $0.33 per share-basic and diluted, down from $1.752 million, or $0.36 per share-basic and diluted for the same quarter in 2016. Net interest income for the third quarter of 2017, after the provision for loan losses, was $6.793 million, approximately 2.4% higher than the same period in 2016. The provision for loan losses for the three months ended September 30, 2017 was negative $74 thousand compared to $183 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 2.98% in the third quarter of 2017 from 3.10% in the same period in 2016. This was due primarily to 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 third quarter of 2017 by $48 thousand, or 2.3%, while non-interest expenses increased $330 thousand, or 5.0%, compared to the same period in 2016. The increase in 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 $285 thousand, occupancy expense of $6 thousand and a $39 thousand increase in other operating expenses. The increase in other non-interest expense was due mainly to office supply costs for the quarter.

Net income for the nine months ended September 30, 2017 decreased 4.5% to $4.828 million, or $0.99 per share-basic and diluted, from $5.057 million, or $1.04 per share-basic and diluted, for the nine months ended September 30, 2016. Net interest income for the nine months ended September 30, 2017, after the provision for loan losses, increased 1.2% to $20.648 million from $20.404 million for the same period in 2016. Net interest margin for the nine months ended September 30, 2017, decreased to 3.03% in 2017 from 3.11% in the same period in 2016. The provision for loan losses for the nine months ended September 30, 2017 was a negative $255 thousand compared to $97 thousand in 2016. The decrease in the provision reflects management’s assessment of inherent losses in the loan portfolio including the impact caused by current local and national economic conditions and a decrease in loans outstanding.

Non-interest income increased by $381 thousand, or 6.6%, and non-interest expense increased by $1.05 million, or 5.3%, for the nine months ended September 30, 2017 when compared to the same period in 2016. The increase in non-interest income was the result of increases in service charges on deposit accounts and other service charges and fees. Non-interest expense increased primarily due to an increase in salary and benefits costs.

Total assets as of September 30, 2017 increased to $1.026 billion, up $910 thousand, or 0.1%, when compared to December 31, 2016. Deposits decreased by $5.387 million, or 0.7%, and loans, net of unearned income, decreased by $972 million, or 0.2%, 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 $1.223 million to $12.305 million at September 30, 2017 as compared to $13.528 million at December 31, 2016, due in large part to decreases in other real estate owned and in non-accrual loans partially offset by a slight increase in loans 90 days or more past due and still accruing interest.

During the nine months of 2017, the Company paid dividends totaling $0.72 per share.
