4 Third Quarter 2025 Highlights Record Net Income Available to Common Stockholders of $180.5 million. Record Diluted Earnings Per Common Share of $1.59. Record Net Interest Income of $413.9 million. Loan Balances – Loans decreased $0.16 billion, or 0.5% not annualized, due to $2.44 billion in Real Estate Specialties Group (“RESG”) loan repayments. Record Deposit Balances – Deposits grew to a record $33.98 billion, an increase of $0.46 billion, or 1.4% not annualized. Asset Quality – Our annualized net charge-off ratios were 0.41% for the quarter and 0.26% for the first nine months of 2025, consistent with our previous guidance. ACL Build – Over the last 13 quarters we have more than doubled our Allowance for Credit Losses (“ACL”) from $300 million to $680 million, including a $14 million increase in the quarter just ended. We believe this ACL build has been a prudent and appropriate response to the shifting mix of risk factors that have driven the challenging and uncertain macroeconomic environment over those 13 quarters. Efficiency Ratio of 35.1%, among the best in the industry. Return on Average Assets of 1.74% (annualized) in the quarter just ended. Capital* – At September 30, 2025, our ratios of total common stockholders’ equity to total assets and total tangible common stockholders’ equity to tangible assets (“TCE ratio”) were 13.83% and 12.44%, respectively. Book Value and Tangible Book Value Per Common Share* – Our book value and tangible book value per common share at September 30, 2025 were $51.09 and $45.23, respectively, increases of $1.50 and $1.51 during the quarter just ended and $4.78 and $4.74 over the last four quarters. Over the last ten years we have consistently increased book value and tangible book value per common share resulting in compounded annual growth rates of 13.1% and 13.2%, respectively. Dividends – We recently increased our dividend on our common stock for the 61st consecutive quarter. Share Repurchases – Our growth in risk-based capital ratios in the quarter just ended has positively influenced our new share repurchase parameters, both price and volume, pursuant to our $200 million stock repurchase program which became effective July 1, 2025. UPDATE: From October 21 through November 3, 2025, we repurchased 600,000 shares for $27.2 million. * The calculations of the Bank’s non-GAAP financial measures and the reconciliations to GAAP are included in the schedules at the end of this presentation.

5 Our goal for 2026 is to improve on the expected record net interest income for the full year of 2025. Achieving this goal will depend on achieving sufficient growth in average earning assets to offset the expected reduction in our net interest margin from loans repricing more quickly than deposits in a declining interest rate environment. Of course, future net interest income will depend on numerous factors, including the timing and magnitude of both growth in earning assets and any Fed interest rate changes. Net Interest Income Trends Our net interest income for the third quarter of 2025 was a record $413.9 million, a 6.3% increase from the third quarter of 2024. Our net interest income for the first nine months of 2025 was $1.19 billion, a 2.7% increase from $1.15 billion for the first nine months of 2024. Our excellent net interest income in the quarter just ended was our second consecutive quarterly record and was consistent with our previous guidance which anticipated record net interest income in one or more quarters of 2025. Assuming two more 25-basis point Fed funds rate cuts this year, we would expect our fourth quarter net interest income to be in the range of the second quarter’s $397 million, more or less. We continue to expect to achieve record net interest income for the full year of 2025. $367 $371 $377 $388 $389 $379 $375 $397 $414 $- $50 $100 $150 $200 $250 $300 $350 $400 $450 3Q23 4Q23 1Q24 2Q24 3Q24 4Q24 1Q25 2Q25 3Q25 Net Interest Income ($ millions)

6 Our loans were $32.85 billion at September 30, 2025, a decrease of $0.16 billion, or 0.5% not annualized, from the record level at June 30, 2025, but an increase of $2.88 billion, or 9.6% not annualized, from December 31, 2024. During the quarter just ended, RESG loan repayments offset excellent growth from Corporate & Institutional Banking (“CIB”) and other lending teams. In the third quarter of 2025, our yield on loans was 7.74%, a decrease of four basis points (“bps”) from the second quarter of 2025 and a decrease of 92 bps from the third quarter of 2024. These decreases reflect the impact on our predominately variable-rate loan portfolio of the cumulative 100-basis point reduction in the Fed funds rate during the last four months of 2024 and some impact of the 25-basis point reduction in September 2025. Trends in Loan Balances and Yields Quarterly Loan Balances & Yields In the fourth quarter of 2025, we expect another quarter of excellent growth from CIB and other lending teams to be offset by elevated RESG repayments, likely resulting in some further contraction in total loan balances. For the full year of 2026, we expect mid-single digit percentage loan growth including strong CIB growth offset by significant RESG loan repayments. Following the expected 2025-2026 RESG elevated repayment cycle, we expect loan growth to increase meaningfully in 2027 and subsequent years with CIB, RESG and our other lending teams all contributing to future growth. $25,332 $26,459 $28,031 $28,674 $29,218 $29,969 $31,108 $33,005 $32,846 8.58% 8.64% 8.70% 8.76% 8.66% 8.17% 7.79% 7.78% 7.74% 0.00% 2.00% 4.00% 6.00% 8.00% 10.00% 12.00% 14.00% $- $5,000 $10,000 $15,000 $20,000 $25,000 $30,000 $35,000 3Q23 4Q23 1Q24 2Q24 3Q24 4Q24 1Q25 2Q25 3Q25 Loan Yield Period-End Loans ($ millions) Period-End Loans Loan Yield

7 In the third quarter of 2025, our tax-equivalent yield on investment securities was 4.25%, decreasing two bps from the second quarter of 2025, but increasing 125 bps from the third quarter of 2024. Our portfolio yield has benefited from the reinvestment, at more favorable rates, of the proceeds from a significant volume of lower-yielding bonds which matured in the final quarter of 2024 and the first two quarters of 2025. Well-Positioned Investment Securities Portfolio Our investment securities, all of which are categorized as available-for-sale, were $2.76 billion at September 30, 2025, decreases of $0.06 billion, or 2.2% not annualized, from June 30, 2025 and $0.08 billion, or 2.7% not annualized, from December 31, 2024. At September 30, 2025, our investment securities had an average effective duration of approximately 5.29 years.

8 Consistent Growth in Deposits to Fund Our Growth in Earning Assets Our deposits were a record $33.98 billion at September 30, 2025, increases of $0.46 billion, or 1.4% not annualized, from June 30, 2025 and $2.94 billion, or 9.5% not annualized, from December 31, 2024. This was our twelfth consecutive quarterly record for deposit balances. Quarterly Deposit Balances & Cost of Interest Bearing Deposits (“COIBD”) In the third quarter of 2025, our COIBD was 3.64%, decreases of six bps and 67 bps, respectively, from the second quarter of 2025 and the third quarter of 2024 reflecting the cumulative 100-basis point reduction in the Fed funds rate during the last four months of 2024 and some impact of the 25-basis point reduction in September 2025. Following each Fed funds rate reduction, our COIBD should move lower over several quarters, but should tend to lag the more immediate decrease in our loan yields. $25,553 $27,405 $29,406 $29,944 $30,572 $31,043 $31,926 $33,522 $33,985 3.48% 3.89% 4.15% 4.24% 4.31% 4.07% 3.78% 3.70% 3.64% 0.00% 1.00% 2.00% 3.00% 4.00% 5.00% 6.00% 7.00% $- $5,000 $10,000 $15,000 $20,000 $25,000 $30,000 $35,000 $40,000 3Q23 4Q23 1Q24 2Q24 3Q24 4Q24 1Q25 2Q25 3Q25 COIBD Period-End Deposits ($ millions) Total Deposits COIBD

Following any Fed interest rate reduction, we anticipate our loan yields will decrease faster than our deposit costs, likely resulting in some decrease in our net interest margin, at least until time deposits reprice and/or floor rates are reached on more variable rate loans (see Page 10). Although no Fed interest rate increases are currently expected, following any Fed interest rate increase, we anticipate our loan yields would increase faster than our deposit costs, likely resulting in some increase in our net interest margin until time deposits reprice. Favorable 1.10% Variance vs Industry* Net Interest Margin vs. the Industry During the quarter just ended, our net interest margin was 4.35%, a decrease of one basis point from the second quarter of 2025, and a decrease of 20 bps from the third quarter of 2024. In the second quarter of 2025, the latest quarter for which comparative data is available, our net interest margin outperformed the industry by 110 bps, continuing our long history of outperformance.

11 Expertise in Diverse Lending Verticals Contributes to Our Favorable Asset Quality, Strong Profitability & Growth We conduct extensive lending operations through our 248* retail branches and 13* loan production offices: ➢ Real Estate Specialties Group (“RESG”) is a nationally recognized leader in commercial real estate construction and development finance. ➢ Our Community Bank originates loans primarily throughout our six-state branch footprint through commercial (generalist) lenders and specialty lending teams. ➢ Corporate and Institutional Banking (“CIB”) includes our Asset Based Lending Group (“ABLG”), Corporate Banking & Sponsor Finance (“CBSF”), Lender Finance Group (“LFG,” formerly the Capital Solutions portion of the previous Equipment Finance & Capital Solutions Group), Fund Finance, Equipment Finance Group (“EFG”), Natural Resources Group (“NRG”) and Loan Syndications & Corporate Services (“LSCS”). These teams primarily focus on non-real estate lending primarily within our branch footprint and secondarily in other markets nationwide. ➢ Indirect RV & Marine lending is a nationwide business originating consumer loans through an extensive dealer network. * As of November 3, 2025.

12 RESG’s percentage of loans declined to 57.7% as of September 30, 2025, compared to 60.0% at June 30, 2025 and an all-time high of 70%. Executing on Our “Growth, Growth and Diversification” Strategy Our long-term goal is for all of our lending teams to grow significantly and with more balance in the portfolio. Of course, opportunities will shift over time, and we will always want to capitalize on the best opportunities. Eventually, we expect CIB’s and RESG’s loan portfolios could be roughly equal in size with each accounting for about one-third of our outstanding loans. The remainder would be a combination of loans from Community Banking and Indirect RV & Marine. We believe such balance and diversification would be very beneficial, while maximizing future growth opportunities. Our “growth, growth and diversification” strategy is achieving greater portfolio diversification through growth in our CIB, Indirect RV & Marine and Community Banking portfolios while continuing to capitalize on the unique strengths and expertise of RESG to contribute to longer term growth. • We expect these other lending teams will continue to contribute meaningfully to further growth and diversification, especially as RESG is likely to continue to have elevated repayments during the remainder of 2025 and in 2026. Implicit in this diversification strategy is an unwavering focus on asset quality from each of these lending teams. • We believe the development and ramp-up of CIB over the past several years was well timed. CIB has achieved significant growth at the same time RESG has absorbed elevated repayments, including record repayments in the quarter just ended. This has resulted in a timely handoff of the “growth baton” from RESG to CIB. • Given our expectation that RESG is likely to have elevated repayments in most quarters through 2026, RESG’s percentage of loans should continue to decline in the remainder of 2025 and 2026, and we expect it will go below 50% during 2026. • Of course, we expect that RESG will resume meaningful growth following its expected 2025 -2026 elevated repayment cycle. 57.7%15.9% 13.6% 12.8% Loan Portfolio as of 9/30/25 9/30/2025 $ millions Balances RESG 18,945$ Community Banking 5,231 CIB 4,470 Indirect Lending 4,200 Total 32,846$

13 Changes in Unfunded Loan Commitments ($ millions) Changes in Funded and Unfunded Balances Changes in Funded Balances of Total Loans ($ millions) During the quarter just ended, CIB loans increased $575 million and Indirect RV & Marine increased $213 million while RESG loans declined $862 million. Community Banking declined $85 million due to the transfer of its $183 million Business Aviation Group portfolio into CIB’s Equipment Finance Group. We expect this diversification trend to continue in future quarters. Consistent with our strategy of greater portfolio diversification, RESG’s percentage of the unfunded loan commitments decreased 6% to 66%, while CIB increased 5% to 26% in the first nine months of 2025. $33,005 $32,846 ( $862 ) ( $85 ) $575 $213 $26,000 $28,000 $30,000 $32,000 $34,000 6/30/25 Balance RESG Community Banking CIB Indirect RV & Marine 9/30/25 Balance 3rd Quarter of 2025 $29,969 $32,846 $389 ( $5 ) $1,920 $573 $26,000 $28,000 $30,000 $32,000 $34,000 12/31/24 Balance RESG Community Banking CIB Indirect RV & Marine 9/30/25 Balance First Nine Months of 2025 $18,392 $17,898 ( $1,209 ) $96 $619 $15,000 $17,500 $20,000 6/30/25 Balance of Unfunded Loan Commitments RESG Community Banking CIB 9/30/25 Balance of Unfunded Loan Commitments 3rd Quarter of 2025 $19,079 $17,898 ( $1,953 ) $75 $697 $15,000 $17,500 $20,000 12/31/24 Balance of Unfunded Loan Commitments RESG Community Banking CIB 9/30/25 Balance of Unfunded Loan Commitments First Nine Months of 2025

14 Started in 2003, RESG is a nationally recognized industry leader in construction, land & development lending and handles our largest and most complex loans. It has historically been our most significant growth engine and should contribute meaningfully to growth in the future. RESG provides superior risk-adjusted returns through a disciplined and differentiated business model. RESG’s industry leading position reflects the fact that throughout its 22-year history we have been open for business every day, in every market, always pursuing the opportunities, and only the opportunities, that meet our rigorous credit quality standards. Our reputation for expertise, consistency, dependability and execution help us maintain our industry leading position. Total funded $18.95 Billion Total funded & unfunded $30.80 Billion RESG Loans at September 30, 2025 accounted for: • 58% of our funded loans • 66% of our unfunded loan commitments • 61% of our total funded and unfunded loan commitments Portfolio Statistics – as of September 30, 2025 *Weighted average; assumes all loans are fully funded; LTV data based on most recent appraisals and utilizing, in most cases, “as stabilized” values for income producing properties. RESG Business Model Reduces Credit Risk • RESG is always the sole senior secured lender, making RESG loans the lowest risk position in the capital stack. • RESG loans are characterized by low leverage, as reflected in its weighted average loan-to-cost (“LTC”) ratio* of 50% and loan- to-value (“LTV”) ratio* of 46% at September 30, 2025. • RESG loans are primarily for ground-up, new construction of high-quality assets which tend to be the most desirable for sale or leasing. • RESG usually works with strong and capable sponsors, including some of the most seasoned and capable developers in the country. • RESG loan documents include defensive structures, providing substantial protection to the bank. ﹣ Loans are typically (i) the last dollars to fund project costs (ii) and the first to be repaid, providing assurance of project completion and loan repayment. ﹣ Many loans also include some combination of preferred equity and mezzanine debt (all subordinate to our senior secured loan) providing repayment support in addition to that of the sponsor. • RESG’s “life of loan” focus utilizes thorough underwriting, rigorous economic analysis, stress testing, comprehensive and consistent documentation, precision at closing and life-of-loan asset management by teams of skilled asset managers.

15 RESG Loan Repayments & Other Activity ($ billions) • Consistent with our guidance, RESG’s loan repayments increased to a record $2.44 billion in the quarter just ended bringing the total for the first nine months of 2025 to $4.24 billion. • The recent increase in debt financing available for projects has also contributed to RESG repayments. • We expect RESG loan repayments will remain elevated in most quarters through 2026. • Loan repayments may vary substantially from quarter to quarter based on a variety of factors including interest rate levels and refinancing alternatives. RESG Originations ($ billions) • RESG loan originations were $0.70 billion in the third quarter and $3.42 billion for the first nine months of 2025. • For some time, many sponsors have faced challenges raising equity capital for new projects as capital partners have been cautious due to macroeconomic uncertainty and tight monetary policy. This has restrained new project starts. • At the same time, a surge in liquidity available for debt financing has created significant competition for the new deals that do raise equity. The current environment of “too many lenders chasing too few deals” has contributed to our subdued RESG origination volume. • We have said for years that origination volume may vary significantly from quarter to quarter and may be impacted by economic conditions, interest rates, competition or other factors. Our reduced level of RESG originations in the quarter just ended reflects the impact of such factors in the current market. • We expect a higher origination volume in the final quarter of 2025.

24 * Data for all FDIC insured institutions from the FDIC Quarterly Banking Profile, last updated second quarter 2025. Annualized when appropriate. Net Charge-Off Ratio (%) (All data annualized where appropriate) In our 28 years as a public company, our net charge-off ratio has outperformed the industry’s net charge-off ratio every year and has averaged only about one-third of the industry’s net charge-off ratio. • We have continued our long track record of having a net charge-off ratio well below the industry average. Our annualized net charge- off ratios were 0.41% for the quarter just ended and 0.26% for the first nine months of 2025, consistent with our previous guidance. • We continue to expect that our full-year 2025 net charge-off ratio will exceed 2024’s 20-bps ratio, but remain below the industry average. Our net charge-off ratio may vary significantly from quarter to quarter . • We have built our portfolio with the goal that it will perform well in adverse conditions, and that discipline has been evident in our recent results through the pandemic, the Fed’s increasing interest rates, higher rates of inflation leading to “higher for longer” interest rate policy, and numerous other sources of macroeconomic, political and geo-political turbulence. • Notwithstanding the considerable uncertainty regarding the macroeconomic and interest rate environment, we expect that our net charge-offs for the full year of 2026 will once again compare favorably to industry metrics.

25 Allowance for Credit Losses (“ACL”) Build Over the Last 13 Quarters As of September 30, 2025, our ACL had increased to $679.6 million, or 1.34% of loans and unfunded loan commitments. This consisted of our allowance for loan losses (“ALL”) at $532.3 million, or 1.62% of loans, and our reserve for losses on unfunded loan commitments at $147.3 million, or 0.82% of unfunded loan commitments. In percentage terms, over those 13 quarters, our ACL has increased from 0.83% to 1.34% of loans and unfunded loan commitments at September 30, 2025. We believe this ACL build has been a prudent and appropriate response to the shifting mix of risk factors that have driven the challenging and uncertain macroeconomic environment over those 13 quarters. $300 $680 $36 $30 $28 $33 $35 $40 $36 $37 $20 $25 $19 $27 $14 0.83% 0.85% 0.87% 0.92% 0.95% 1.00% 1.07% 1.11% 1.19% 1.23% 1.26% 1.28% 1.30% 1.34% 0.50% 0.60% 0.70% 0.80% 0.90% 1.00% 1.10% 1.20% 1.30% 1.40% $200 $250 $300 $350 $400 $450 $500 $550 $600 $650 $700 $750 ACL at 6/30/22 3Q22 4Q22 1Q23 2Q23 3Q23 4Q23 1Q24 2Q24 3Q24 4Q24 1Q25 2Q25 3Q25 ACL at 9/30/25 ACL % of Total Loans + Unfunded Commitment ACL Period End Balances & Qtly.

26 Portfolio Credit Quality Trends ($ millions) At September 30, 2025, our ratio of loans 30 or more days past due to total loans was 0.14% compared to 0.15% at June 30, 2025 and 0.14% at September 30, 2024; our ratio of nonperforming loans to total loans was 0.46% compared to 0.18% at June 30, 2025 and 0.60% at September 30, 2024; and our ratio of nonperforming assets to total assets was 0.55% compared to 0.53% at June 30, 2025 and 0.68% at September 30, 2024. We have seen a reasonably well-contained migration of risk ratings and credit quality metrics since the Federal Reserve initiated its most recent tightening cycle. During the third quarter, we had a modest net reduction in total classified and criticized assets as summarized below. The significant changes included (i) liquidation of our largest foreclosed asset with net proceeds equal to its carrying value; (ii) migration of one RESG credit from substandard accrual to substandard non-accrual with a partial charge-off; (iii) migration of one RESG credit from special mention to substandard non-accrual with a partial charge-off; and (iv) migration of one RESG credit from special mention to substandard accrual.

28 An important element of our business model is to structure loans so that sponsors and their capital partners are highly incentivized to support the loans, even in challenging times. To achieve this, we obtain sizable equity investments relative to our low leverage loans, assuring that sponsors/capital partners are likely to have too much invested to walk away. Additionally, we focus on loans secured by high quality assets that have good long-term prospects, which motivates sponsors to stay engaged, even if sales or leasing take more time than expected. Demonstrated Sponsor/Capital Partner Support of RESG Loans # of Index Floors▲: 200 # of Index Floors ▼: 1 # of Spreads▲: 11 # of Spreads▼: 5 Enhancements # of Modifications & Extensions Additional Reserve Deposits Unscheduled Paydowns Reductions in Unfunded Amount The effectiveness of our approach is evident in our results since the Federal Reserve started increasing the Fed funds target rate. We have seen significant support by sponsors/capital partners for our RESG loans, evidenced by the $1.2 billion of total additional equity contributions ($809 million of additional reserve deposits and $384 million of unscheduled paydowns) received related to the 541 modifications/extensions. Additionally, we enhanced our floor rates and spreads on 200 loans and 11 loans, respectively, while granting 1 floor reduction and 5 spread reductions over the last 13 quarters.

30 Because of the substantial “retail” nature of our deposit base, 79% of our deposits are either insured (64% at September 30, 2025) or, in the case of public funds and certain other deposits, collateralized (15% at September 30, 2025). As of September 30, 2025, our average account balance was approximately $49,000. The diversity of our deposit base is an important factor in the demonstrated stability of our deposits. Diverse & Growing Deposit Base and Substantial Liquidity Sources Primary and Secondary Liquidity Sources: We maintain substantial and diverse sources of primary and secondary liquidity. At September 30, 2025 these sources totaled $15.6 billion, consisting of $3.1 billion of cash and cash equivalents, $1.9 billion of unpledged investment securities, $8.8 billion of available FHLB borrowing capacity, $1.2 billion of available unsecured lines of credit and $0.6 billion of Fed discount window borrowing availability.
