Conservative & Stable Investment Portfolio Management Our investment portfolio is prudently managed, with a focus on short-term, high-quality, liquid securities. Our portfolio is approximately 11% of our assets, it serves as collateral for public deposits and provides liquidity for our bank. At March 31, 2023, our AFS securities totaled $625 million with a duration of 2.3 years and HTM securities totaled $938 million with a duration of 5.8 years. Available Sources of Liquidity Historically, our bank experiences minimal deposit growth during the first quarter. Year to date we have continued to fund our bank with core deposits and relationship banking. We have no borrowings with the FHLB. We have loans pledged to the FHLB providing approximately $1.4 billion in available funding. We have additional unpledged CRE loans that would provide approximately $1.7 billion in additional funding through the FHLB for a total of $3.1 billion. The bank also has $402.5 million in unpledged securities that can be pledged for liquidity. We have no brokered deposits but our policy allows for brokered deposits of up to 25% of total assets.

Credit Since the bank’s founding we have focused our calling efforts on owner operated C&I companies in the Southeast. Almost half of our loan portfolio is comprised of C&I and Owner Occupied Real Estate loans, which is among the highest in our industry. The average remaining maturity of our commercial loan portfolio is 3.5 years. Pristine Credit Quality Charge-offs for the first quarter were only $1.5MM or 5 basis points (bps) annualized. Non Performing Loans to Total Loans were 15bps which is near our historical lows. Past Dues to total loans were 17bps for the quarter. Loan loss reserve was 1.28% of total loans at quarter-end, up from 1.25% at year end. Commercial Real Estate Office Exposure represents less than $388 million, or 3.3% of total loans with an average loan size of $1.5MM and typically in suburban settings. Our largest office exposure credit is a $21 million suburban medical office building with a strong sponsor. Loans secured by multifamily properties total $1.36 billion or 11.7% of total loans. These projects are focused in the Sun Belt and the bank generally has 30% - 35% equity upfront. Single family residential development represents $258 million in exposure, or 2.2% of total loans. Lot and Land exposure represents $267 million in exposure, or 2.3% of total loans. AD&C loans as a percent of capital decreased to 93% at 3/31 down from 100% at year-end. 7
