Returning to the original form for position after being bent, compressed or stretched. Recovering readily from illness, depression, adversity, or the like; buoyant. Random House Xxxxxxx’x Unabridged Dictionary Second Edition. Another good word is strong. An even better word is tough. These are words that describe what First Guaranty has been during a six month period in which we have survived wound after wound, not of our own causing as we continue to deliver to our shareholders, customers, and our staff members extraordinary results. The latest of these have been the FDIC deposit insurance adjustment which was $450,000 for the second quarter. Enough crying over spilt milk. This is what we did to make it better. Our interest income for the second quarter of 2023 increased to $43,781,000 compared to $32,540,000 for the second quarter of 2022. For the six months ending June 30, 2023, our interest income totaled $85,068,000 compared to $63,019,000. Our interest expense stabilized at $22,868,000 for the quarter compared to $41,854,000 for the six month period ending June 30, 2023. We have significantly increased our loan interest income to offset the increased cost of deposits which are set by the Federal Reserve. For the quarter, we made over $2,000,000 for our shareholders even after the FDIC assessment. Basically, we have and will continue to make a lot of money for our shareholders. We are working very hard to control non-interest expense. We are working very hard to expand our interest margin. Our lenders have done a great job working to increase the rates we receive for our loans. Let’s keep moving forward. Let’s be resilient. Let’s be TOUGH. Thank you for your attention. Xxxxx X.
