OUR STRATEGY Organic Loan Growth: Take advantage of platform that we have developed post 2015 recapitalization, capitalize on fragmented Miami-Dade MSA community banking market, and continue to build market share Capitalize on inherent advantages over smaller community banks which lack our product expertise and breadth of service Due to significant consolidation, there exists a base of potential clients that desire to partner with a bank that is locally headquartered Team Lift-outs: Continue to bring in top tier talent to U.S. Century Bank, with teams attracted to culture, public currency and local decision making Overall growth success will depend upon our ability to attract, retain, develop, incentivize, and reward the human capital necessary to execute growth strategy Attractive stock-based incentive compensation to attract top tier talent Asset purchases Portfolio loan purchases; opportunistic to complement organic growth initiatives Net capital can serve as dry powder to facilitate meaningfully sized portfolio acquisitions Proactively evaluating portfolio opportunities that are consistent with USCB’s credit philosophy Strategic Acquisitions: Become an active acquirer for Florida banks looking to find a partner Focused on strategic, financially attractive acquisitions which support USCB’s organic growth strategy without compromising the risk profile Numerous potential partners in Miami-Dade MSA that may seek liquidity USCB is positioned to offer stock consideration 9
