CITIZENS HOLDING COMPANY REPORTS EARNINGS

PHILADELPHIA, Miss.—(BUSINESS WIRE)—July 20, 2012—Citizens Holding Company (NASDAQ:CIZN) announced today results of operations for the three and six months ended June 30, 2012.

Net income for the three months ended June 30, 2012 was $1.752 million, or $0.36 per share-basic and diluted, down from $1.854 million, or $0.38 per share-basic and diluted for the same quarter in 2011. Net interest income for the second quarter of 2012, after the provision for loan losses for the quarter, was $7.216 million, approximately 1.9% higher than the same period in 2011, due to a decrease in the provision for loan losses offset partially by a decrease in net interest income. The provision for loan losses for the three months ended June 30, 2012 was $330 thousand compared to $683 thousand for the same period in 2011. 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. The net interest margin decreased to 4.16% in the first quarter of 2012 from 4.29% in the same period in 2011 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 2012 by $121 thousand, or 8.0%, while non-interest expenses increased $428 thousand, or 6.9%, compared to the same period in 2011. The increase in non-interest income was due primarily to an increase in service charges on deposit accounts and other service charges and fees. Non-interest expenses increased due to a $399 thousand increase in other operating expense and a $79 thousand increase in occupancy expense offset by a $50 thousand decrease in salaries and benefits.

Net income for the six months ended June 30, 2012 decreased 10.3% to $3.415 million, or $0.70 per share-basic and diluted, from $3.809 million, or $0.79 per share-basic and diluted, for the six months ended June 30, 2011. Net interest income for the six months ended June 30, 2012, after the provision for loan losses, decreased 2.4% to $14.068 million from $14.413 million for the same period in 2011. Net interest margin for the six months ended June 30, 2012, decreased to 4.13% in 2012 from 4.28% in the same period in 2011. The provision for loan losses for the six months ended June 30, 2012 was $866 thousand compared to the provision of $927 thousand in 2011. 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 $147 thousand, or 4.7%, and non-interest expense increased by $438 thousand, or 3.7%, for the six months ended June 30, 2012 when compared to the same period in 2011. 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 increased primarily due an increase in other operating expenses of $426 thousand and occupancy expenses in the amount of $22 thousand partially offset by a decrease in salaries and benefits in the amount of $10 thousand.

Total assets as of June 30, 2012 decreased to $844.781 million, down $9.164 million, or 1.1%, when compared to December 31, 2011. Deposits increased by $19.234 million, or 3.4%, and loans, net of unearned income decreased by $5.039 million, or 1.3%, when compared to December 31, 2011. The decrease in loans, net of unearned, was due to declining loan demand and repayments of existing loans. Non-performing assets decreased by $805 thousand to $15.632 million at June 30, 2012 as compared to December 31, 2011, because of decreases in non-accrual loans and other real estate owned partially offset by an increase in loans 90 days or more past due and still accruing interest.

During the first half of 2012, the Company paid dividends totaling $0.44 per share.
