We have supported our markets by hiring a number of experienced in-market bankers and banking teams. In 2024, we entered our Southeast market, consisting of South Alabama and the Florida Panhandle, with two banking locations staffed with experienced relationship bankers and their support personnel. To support our growth, we have raised over $589.6 million of new Tier 1 capital since 2006, including proceeds from our initial public offering completed in May 2018, we issued subordinated notes that are treated as Tier 2 capital for regulatory purposes in 2020, and we completed an all stock merger valued at $307.8 million in 2022. Through these efforts, we have successfully increased our market share in our key geographic markets. Our Competitive Strengths and Banking Strategy Organic Growth Capabilities with Strategic Acquisitions We have historically been able to demonstrate our ability to grow our loans and deposits organically. Our team of seasoned bankers has been an important driver of our organic growth by further developing banking relationships with current and potential clients. Our relationship bankers are motivated to increase the size of their loan and deposit portfolios and generate fee income while maintaining strong credit quality. To promote our organic growth, we strategically locate banking centers within our markets and employ highly experienced relationship bankers who proactively develop valuable relationships within the communities that we serve. Through these relationships, our bankers are able to meet our customers’ needs and capitalize on loan demand across a wide range of industries. This allows us to not only diversify our loan portfolio, but also focus on loans with quality credit characteristics. We focus on generating and retaining core deposits as our primary funding source to support loan growth. We believe motivating our relationship bankers to generate strong deposit growth enhances our ability to build and strengthen client relationships and provide stable funding for future growth.…
