PEOPLES FINANCIAL CORPORATION REPORTS RESULTS FOR

THIRD QUARTER OF 2015

BILOXI, MS (October 28, 2015 ) — Peoples Financial Corporation (NASDAQ Capital Market: PFBX), parent of The Peoples Bank, reported a net loss of $2,553,000 for the third quarter of 2015, announced Chevis C. Swetman, chairman and chief executive officer of the holding company and the bank.

Impacting the company’s net loss for the third quarter of 2015 was a loss of $1,695,000 from the credit impairment of bonds issued by a municipality. Principal and interest payments due under the current terms of the bonds are to be funded by property tax collections by the related municipality. The impairment loss is the result of a significant reduction in the assessed value of the related real estate parcels, which has reduced the expected cash flows to be collected. Accrued interest of $92,564 relating to these securities was charged off during the third quarter of 2015.

Financial results for the third quarter of 2015 include significant improvement in the company’s asset quality. The provision for loan losses for the third quarter of 2015 was $285,000 compared to $3,541,000 for the same period last year. The loan loss provision decrease over the prior year was primarily related to the improved quality of the loan portfolio. Charge-offs decreased during the third quarter of 2015 to $1,580,000 compared to $2,244,000 for the same period last year. Non-accrual loans as of September 30, 2015 were $18,658,000 compared to $33,451,000 as of September 30, 2014. The allowance for loan losses as a percentage of total loans was 2.40% as of September 30, 2015 compared to 3.07% as of September 30, 2014.

As of September 30, 2015, Other Real Estate (“ORE”) was $10,867,000 compared to $9,710,000 at September 30, 2014. ORE for the third quarter of 2015 includes results from the company’s auctioning of 18 real estate parcels with a carrying value of $1,768,112 for a loss of $857,815. Foreclosures year to date for 2015 totaled $7,279,000 compared to $1,144,000 year to date for 2014 while sales of ORE year to date 2015 totaled $3,615,000 compared with $845,000 year to date for 2014.
