PEOPLES FINANCIAL CORPORATION FIRST QUARTER 2013 EARNINGS

INCREASE 20% OVER FIRST QUARTER 2012

BILOXI, MS (April 25, 2013)—Peoples Financial Corporation (NASDAQ Capital Market: PFBX), parent of The Peoples Bank, reported net income of $606,000 for the first quarter of 2013, a 20% increase over the first quarter of 2012, announced Chevis C. Swetman, Chairman and Chief Executive Officer of the holding company and the bank.

Earnings per weighted average share for first quarter of 2013 increased to $.12, compared to $.10 per average weighted share in the first quarter of 2012. Earnings per share figures are based on weighted average common shares outstanding of 5,136,771 and 5,136,918, respectively for the three-month periods ended March 31, 2013 and March 31, 2012.

“Our financial results for the first quarter reflect the continued gradual recovery of our area’s economy,” said Swetman. “Our nonaccrual loans fell below $50 million during the quarter, nearly 13% below the level of a year ago, which represents a good direction,” he added.

First quarter provision for loan losses totaled $539,000, slightly less than $540,000 for the same period last year. At the same time, the allowance for loan losses as a percentage of total loans increased to 2.12%, compared to 1.88% in the same period last year.

The bank’s primary capital ratio stood at 14.33% at the end of the first quarter of 2013, compared to 13.51% at the end of the same period in 2012.
