PEOPLES FINANCIAL CORPORATION EARNS $335,000 IN SECOND QUARTER

OF 2014, REVERSING LOSS IN SAME PERIOD OF 2013

BILOXI, MS (July 23, 2014)—Peoples Financial Corporation (NASDAQ Capital Market: PFBX), parent of The Peoples Bank, reported net earnings of $335,000 for the second quarter of 2014 and $914,000 for the first half of the year, announced Chevis C. Swetman, Chairman and Chief Executive Officer of the holding company and the bank.

Second quarter profits reversed a loss of $1,147,000 in the same period last year caused primarily by a $3,538,000 provision for loan loss mostly related to one out-of-area residential development loan. The loan loss provision for the second quarter of 2014 totaled $537,000, which is in line with provisions of most other quarters during the past three years.

Earnings per weighted average common share for the second quarter of 2014 were $.07 compared to a loss of $.23 per weighted average common share in the second quarter of 2013. Losses and earnings per share figures are based on weighted average common shares outstanding of 5,123,186 and 5,132,494, respectively, for the three-month periods ended June 30, 2014 and June 30, 2013.

The $914,000 in net earnings for the first half of 2014 reversed a $541,000 loss for the same period in 2013.

Earnings per weighted average common share for the first half of 2014 were $.18 compared to a loss of $.11 per weighted average common share in the first half of 2013. Losses and earnings per share figures are based on weighted average common shares outstanding of 5,123,186 and 5,134,620, respectively, for the six months ended June 30, 2014 and June 30, 2013.

“After a very difficult year in 2013, our bank’s results have been positive so far in 2014,” said Swetman. “We have scrubbed our balance sheet, and we have been able to resume our semi-annual dividend, which demonstrates the confidence our Board has in our future operations,” he added.

Nonaccruing loans continued to decrease in second quarter 2014 from first quarter this year and now total less than half the amount on the books at the same time last year. Loans past due 90 days and still accruing have decreased to $512,000 as of June 30, 2014, down from $1,713,000 as of June 30, 2013.

The net interest margin for the six months ended June 30, 2014 rose to 3.42%, compared to 2.96% the same period in 2013. “This improvement of 46 basis points in our margins represents another positive metric in our operations,” said Swetman.

The bank’s primary capital ratio rose to 14.88% at the end of the second quarter of 2014, compared to 14.20% at the end of the same period in 2013.

Founded in 1896, with $739 million in assets as of June 30, 2014, The Peoples Bank operates 17 branches along the Mississippi Gulf Coast in Hancock, Harrison, Jackson and Stone counties. In addition to a comprehensive range of retail and commercial banking services, the bank also operates a trust and investment services department that has provided customers with financial, estate and retirement planning services since 1936.
