For more than a decade, we have deliberately built our business to become a national commercial bank focused on deep segment expertise, underwriting specialization and business diversification, including a broad range of differentiated deposit-generating businesses. This agile business model — and the robust relationships we have built with our varied stakeholders — has served us well in building a strong liquidity foundation, which we believe positions us as a strong company today that is prepared for the long term.

·Invest proactively in people, technology, and risk management to support efficient growth, regulatory readiness, and seamless scalability beyond the $100 billion asset threshold.

ABOUT US

Stockholder Engagement

We maintain an ongoing, proactive outreach effort with our stockholders in a variety of ways. Throughout the year, our Investor Relations team and executive leaders regularly meet with current stockholders, prospective investors and research analysts. These meetings often include our Chief Executive Officer (“CEO”), Chief Financial Officer (“CFO”), chief banking officers or line of business leaders to engage stockholders and solicit feedback on various topics relevant to the Company’s performance and strategy. Our executive management team provides context to our stockholders on our diversified business model and funding strategy, balance sheet optimization efforts and asset quality. Additionally, we continued to provide insightful disclosures to address stockholder inquiries related to drivers of ongoing earnings growth, sources of deposit growth and loan originations, and our demonstrated, consistent credit culture. During 2025, management attended numerous investment analyst-sponsored industry conferences and conducted non-deal roadshows to meet with existing and prospective investors. The feedback received from our stockholders is communicated to business leaders and the Board of Directors (the “Board” or “Board of Directors”), and helps inform our business decisions and strategy, when appropriate.
