October 2021 Investor Presentation • Most Recent Quarter Recap • Company Overview • Lending Overview • Deposit Overview • Financials 3 AGENDA

October 2021 Investor Presentation4 MOST RECENT QUARTER HIGHLIGHTS Consistent Profitability • Pre-tax pre-provision ROAA and ROAE were 1.78% and 15.08%, respectively, for the quarter ended September 30, 2021, and 1.72% and 14.11%, respectively, for the same quarter in the prior year. • Management remains focused on disciplined expense management with increases in the current quarter being largely correlated to, merger and acquisition costs, the opening and buildout of loan production offices and the timing of donation and advertising activities. • Our efficiency ratio was 52.9% during the first nine months of 2021, compared to 59.6% during the same nine-month period of the prior year. Growth to Drive Results • Organic non-PPP loan production levels were $303 million, a 6.3% increase over the trailing quarter, while gross payoffs also grew to $244 million or a 27.1% increase over the trailing quarter. • While the start-up costs associated with newly opened loan production offices currently exceed revenues, those loan production teams have generated more than $60 million of in-process underwriting volumes • Management is actively monitoring a variety of acquisition opportunities. Net Interest Income and Margin • Net interest margin (FTE) was 3.50% for Q3 2021, compared to 3.58% for Q2 2021, and 3.72% in Q3 2020. Compression in NIM has been driven by growth in the investment security portfolio as a percent of average total earning assets which was 27.7% at Q3 2021 compared to 20.2% at Q3 2020. • Growth in non-interest-bearing deposits continue to drive improved funding costs where total cost of deposits was 0.05% in Q3 2021 compared to 0.09% Q3 2020. Credit Quality • Excluding PPP, loan loss reserves were 1.78% of total loans compared to 1.83% as of June 30, 2021 and 2.07% as of December 31, 2020 . • Approximately 98% of all round one and 25% of all round two PPP loans have been forgiven by the SBA. • Meaningful decreases in the volume of COVID related loan payment deferral modifications, the balance of total non-performing loans, and a continued low ratio of classified loans to total loans. Diverse Deposit Base • Non-interest-bearing deposits comprise 40.7% of total deposits, and core deposits have grown 14.1% YOY Capital Strategies • Strength in core earnings is key to self-financed and self-funded growth. • We remain well capitalized across all regulatory capital ratios. • Consistent quarterly dividend payments with a history of periodic increases. • Active share repurchase program with demonstrated utilization, albeit currently on hold as a result of the pending merger.
