Announces Third Quarter 2021 Results Hammond , Louisiana , October 25 , 2021 - First Guaranty Bancshares , Inc. ( " First Guaranty " ) ( NASDAQ : FGBI ) , the holding company for First Guaranty Bank , announced its unaudited financial results for the quarter ending September 30 , 2021 . The third quarter of 2021 gives evidence of the strength , the resilience , and the progress of First Guaranty Bancshares , Inc. over the past few years . The third quarter of 2021 brought record earnings and shareholder value in spite of Hurricane Ida and in spite of the continued obstacles of Covid - 19 . Continued strong loan demand resulted in loan interest income of $ 26,685,000 for the quarter compared to $ 22,519,000 for the same quarter of 2020 , an increase of approximately 20 % . At the same time , our interest expense reduction efforts resulted in a decrease in total interest expense of approximately 10 % . The combination resulted in net interest income , after provision for loan losses , for the quarter of $ 23,528,000 compared to $ 17,494,000 for the same quarter of 2020 ; an increase of approximately 35 % . At the same time , due to our emphasis on expense control , non - interest expense increased only 8.5 % . The net income available to common shareholders improved from , for the quarter , $ 5,182,000 to $ 7,209,000 , an increase in net income available to common shareholders of approximately 40 % . Strong progress . Our loan pipeline indicates that we will continue to make strong progress . Because of forgiveness of PPP , our loan portfolio for the quarter did not increase significantly ; however , the fact that we replaced PPP loans with core loans , because of the difference in yield , we will increase income by approximately $ 1,000,000 without any significant difference in our balance sheet . This is the type of management and progress we expect to continue . And , in case you didn't know this , we have been selected by Newsweek and Lending Tree , for the second year in a row as the Best Small Bank in the United States . Our championship last year was not a one - time flash . We have shown that we have the quality and consistency to repeat . We will continue to build a strong , fortress balance sheet . We will continue to enhance shareholder value . Thank you for your support . Sincerely , Alton B. Lewis President and CEO First Guaranty , Bancshares , Inc.
