First Guaranty Bancshares, Inc. Announces Fourth Quarter 2023 Results

Hammond, Louisiana, February 5, 2024 – First Guaranty Bancshares, Inc. ("First Guaranty") (NASDAQ: FGBI), the holding company for First Guaranty Bank, announced its unaudited financial results for the quarter and year ending December 31, 2023.

2024!!!!!!! Happy New Year!!!!! We are happy to see 2023 in our rearview mirror. We survived the Silicon Valley adventure and now we have survived the Fed interest rate adventure. And we didn’t just survive, we made money. Our loan volume continued to be strong and continues to be strong. The loan volume grew year over year from $2,519,077,000 to $2,748,708,000. We have tightened down on our expenses and we have used this opportunity to clean our loan portfolio.

What does this mean? It means that we are completing our 90th year and we are completing it with new heights in capital, with new heights in assets. Assets grew year over year from $3,151,347,000 to $3,552,772,000. We are in new heights in loans and loan interest income.

We have taken everything that can be thrown at us and we have not only survived, we have continued to grow and we have continued to make money, not as much as we want to, but we continue to make money. So now, in 2024 we are ready to move forward. We are ready to make our 91st year a year of new heights for First Guaranty Bancshares, Inc. and for the shareholders of First Guaranty Bancshares, Inc.

Thank you for your continued support.

Sincerely,

Alton B. Lewis

President and CEO

Non-GAAP Financial Measures

Our accounting and reporting policies conform to accounting principles generally accepted in the United States, or GAAP, and the prevailing practices in the banking industry. However, we also evaluate our performance based on certain additional metrics. Tangible book value per share and the ratio of tangible equity to tangible assets are not financial measures recognized under GAAP and, therefore, are considered non-GAAP financial measures.

Our management, banking regulators, many financial analysts and other investors use these non-GAAP financial measures to compare the capital adequacy of banking organizations with significant amounts of preferred equity and/or goodwill or other intangible assets, which typically stem from the use of the purchase accounting method of accounting for mergers and acquisitions. Tangible equity, tangible assets, tangible book value per share or related measures should not be considered in isolation or as a substitute for total shareholders' equity, total assets, book value per share or any other measure calculated in accordance with GAAP. Moreover, the manner in which we calculate tangible equity, tangible assets, tangible book value per share and any other related measures may differ from that of other companies reporting measures with similar names.

The following table reconciles, as of the dates set forth below, shareholders' equity (on a GAAP basis) to tangible equity and total assets (on a GAAP basis) to tangible assets and calculates our tangible book value per share.
