CITIZENS HOLDING COMPANY REPORTS EARNINGS

PHILADELPHIA, Miss.—(BUSINESS WIRE)—July 26, 2013—Citizens Holding Company (NASDAQ:CIZN) announced today results of operations for the three and six months ended June 30, 2013.

Net income for the three months ended June 30, 2013 was $1.604 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 2012. Net interest income for the second quarter of 2013, after the provision for loan losses for the quarter, was $6.231 million, approximately 13.7% lower than the same period in 2012, due to an increase in the provision for loan losses and a decrease in net interest income. The provision for loan losses for the three months ended June 30, 2013 was $574 thousand compared to $330 thousand for the same period in 2012. The increase in the provision reflects management’s estimate of inherent losses in the loan portfolio including the impact of current local and national economic conditions. The net interest margin decreased to 3.48% in the second quarter of 2013 from 4.16% in the same period in 2012 primarily because of the decrease in yields on earning assets was greater than the decline in rates paid on interest bearing deposits.

Non-interest income increased in the second quarter of 2013 by $292 thousand, or 17.8%, while non-interest expenses decreased $528 thousand, or 7.9%, compared to the same period in 2012. The increase in non-interest income was due primarily to an increase in service charges on deposit accounts, other income and other service charges and fees. Non-interest expenses decreased due to a $403 thousand decrease in other operating expense and a $138 thousand decrease in salaries and benefits offset by a $13 thousand increase in occupancy expense. The decrease in other operating expense was due mainly as a result of lower regulatory and related costs.

Net income for the six months ended June 30, 2013 decreased 11.6% to $3.018 million, or $0.62 per share-basic and diluted, from $3.415 million, or $0.70 per share-basic and diluted, for the six months ended June 30, 2012. Net interest income for the six months ended June 30, 2013, after the provision for loan losses, decreased 9.2% to $12.812 million from $14.038 million for the same period in 2012. Net interest margin for the six months ended June 30, 2013, decreased to 3.50% in 2013 from 4.13% in the same period in 2012. The provision for loan losses for the six months ended June 30, 2013 was $749 thousand compared to the provision of $866 thousand in 2012. 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.

Non-interest income increased by $363 thousand, or 11.2%, and non-interest expense decreased by $380 thousand, or 2.9%, for the six months ended June 30, 2013 when compared to the same period in 2012. The increase in non-interest income was primarily due to an increase in service charges from deposit accounts and other service charges and fees. Non-interest expense decreased primarily due a decrease in other operating expenses of $84 thousand and in salaries and benefits in the amount of $391 thousand partially offset by an increase in occupancy expenses in the amount of $95 thousand. The decrease in other operating expense was due mainly as a result of lower regulatory and related costs.

Total assets as of June 30, 2013 decreased to $866.662 million, down $14.178 million, or 1.6%, when compared to December 31, 2012. Deposits increased by $10.606 million, or 1.7%, and loans, net of unearned income decreased by $5.863 million, or 1.6%, when compared to December 31, 2012. The decrease in loans, net of unearned, was due to declining loan demand and repayments of existing loans. Non-performing assets decreased by $669 thousand to $18.733 million at June 30, 2013 as compared to December 31, 2012, because of decreases in non-accrual loans, other real estate owned and loans 90 days or more past due and still accruing interest.

During the first half of 2013, the Company paid dividends totaling $0.44 per share.
