A number of factors, many of which are beyond our control, could cause actual results to differ materially from future results expressed or implied by such forward-looking statements. These factors include, but are not limited to, (1) the credit quality of our loan portfolio, (2) general economic conditions and related material risks and uncertainties in the United States, globally and in our markets and the impact they may have on us and our customers, including the continued impact on our customers from volatility in oil and gas prices as well as the continued impact of the COVID-19 pandemic (and any other pandemic, epidemic or health-related crisis), (3) technological changes, including the increased focus on information technology and cybersecurity and our ability to manage such information systems and the effects of cyber-incidents (including failures, disruptions or security breaches) or those of third-party providers, (4) changes in interest rates and changes in the value of commercial and residential real estate securing our loans, (5) adverse economic or market conditions that could affect the credit quality of our loan portfolio or our operating performance, (6) expectations regarding rates of default and credit losses and the appropriateness of our allowance for credit losses and provision for credit losses, (7) unexpected market conditions, regulatory changes or changes in our credit ratings that could, among other things, cause access to capital market transactions and other sources of funding to become more difficult, (8) the inadequacy of our available funds to meet our obligations, (9) the failure to effectively balance our funding sources with cash demands by depositors and borrowers, (10) material failures of our accounting estimates and risk management processes based on management judgment, (11) failure of our risk management strategies and procedures, including failure or circumvention of our controls, (12) the failure to effectively manage risk, (13) uncertainty regarding the London Interbank Offered Rate and our ability to successfully implement any new interest rate benchmarks, (14) the impact of changing regulatory requirements and legislative changes on our business, (15) the failure to successfully execute our business strategy, including completing planned merger, acquisition or sale transactions, (16) the failure to identify, attract and retain key personnel or the loss of such personnel, (17) increased or more effective competition from banks or other financial service providers in our markets, (18) structural changes in the markets for origination, sale and servicing of residential mortgages, (19) certainty in the pricing of mortgage loans that we purchase, and later sell or securitize, (20) volatility in the market price of our common stock, (21) credit risk resulting from our exposure to counterparties, (22) an increase in the incidence or severity of fraud, illegal payments, security breaches and other illegal acts impacting us, (23) the failure to maintain adequate regulatory capital to support our business, (24) environmental liability or other environmental, social or governance factors that may materially negatively impact the company, (25) severe weather, natural disasters, acts of war or terrorism and other external events and (26) our success at managing the risk and uncertainties involved in the foregoing factors. These and other factors that could cause results to differ materially from those described in the forward-looking statements, as well as a discussion of the risks and uncertainties that may affect our business, can be found in our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q and in other filings we make with the Securities and Exchange Commission (the “SEC”).

12 Our Aspiration Defined Challenges to be Addressed Our Path Forward Our Deliverables

13 Defined Challenges to be Addressed (1 of 2) Challenges to Overcome Limited Fee Income and Unfocused Loan Growth Relatively low client relevance resulting from narrow product offerings led to an overdependence on loan growth to drive earnings Actions to Date  Initiated a detailed action plan (e.g., processes, tools, technology) to expand offerings to current and prospective clients and become a full-service financial services firm  Instituted Balance Sheet Committee to instill a “client first” focus concurrent with capital discipline to invest in the best clients in our markets and drive broad long-term relationships  Improving front-line support loading and gearing to enable bankers to spend more time with clients Funding Strategy Overreliance on disconnected, high-cost, high-beta national deposit verticals created headwinds to earnings growth and volatility as rates normalized  Narrowing the focus to emphasizing relationships with core clients, then supplementing with select franchise value-accretive verticals to improve the funding profile and increase the mix of stable operating deposits  Investing in partnerships and expertise to fully develop Treasury product offerings  Proactively managing excess liquidity to improve balance sheet efficiency, while extending duration via the securities portfolio to reduce earnings variability through the rate cycle Lower-than-Peer Capital Ratios Utilizing leverage to drive financial performance limited ability to proactively manage capital and take advantage of market opportunities  Executed $300.0 million preferred offering  Closed on $375.0 million of new sub-debt  Completed a first-of-its-kind mortgage warehouse credit risk transfer  Capital levels are now consistent with the internal targets we are committed to maintaining going forward Defined Challenges… Our Vision… Our Values Our Competitive…

14 Defined Challenges to be Addressed (2 of 2) Challenges to Overcome Cyclical Portfolio Concentrations Poor client selection in select areas led to sizeable charge-offs ($273 million over two years, 2019 and 2020), while ill-advised larger holds led to overexposure in the wrong sectors and suboptimal risk-adjusted returns  Providing discipline via the Balance Sheet Committee and new risk culture to ensure capital is directed to achieve our goal of earning broad, long-term relationships  Strengthened credit risk management to align with the businesses on client selection ensuring adherence to appropriately established concentration and hold limits Actions to Date Misallocated Expenses Legacy investment agenda not tied to strategy focused little on core banking infrastructure while prioritizing hobby, incompatible technology and costly builds for non-core new businesses Investments not as beneficial due to operational silos and lack of commensurate focus on changing adjacent processes  Developed well-defined and disciplined operating routines focused on re-underwriting every dollar of expense to ensure appropriate focus, adoption, and return  Transitioned the Correspondent Lending business to not only meaningfully improve thru- cycle earnings variability, but also enhance our run-rate expense base (~$70 million). Saves are already being redeployed into banker hires, enhancing existing platforms, and expanding products Operating Model Not Ready for Scale A siloed mindset and organizational structure anchored to past success limited our ability to evolve at the pace necessary for the next phase of growth  Established organizational routines to ensure resources are effectively allocated against strategic priorities. All necessary parties are at the table to expedite decisions, which once made can be executed on throughout the organization  Executive leadership implemented an expectation of clear communication, execution, transparency, and accountability throughout the enterprise Defined Challenges… Our Vision… Our Values Our Competitive…

38 Our Deliverables – Footnotes 1. ROTCE is a non-GAAP financial measure. ROTCE represents the measure of net income available to common shareholders as a percentage of average tangible common equity. ROTCE is used by management in assessing financial performance and use of equity. A reconcilement of ROTCE to the most directly comparable U.S. GAAP measure, ROCE, for 2019 and 2Q21 is below. We are not providing a quantitative reconciliation of ROTCE to ROCE for 2025 because we are unable to predict with reasonable certainty the ultimate outcome of certain significant items that could have a material impact on the U.S. GAAP reported results for the guidance period because they have not yet occurred, are out of our control, and/or cannot be reasonably predicted without unreasonable effort 2.
