Rhea-AI Filing Summary

FirstSun Capital Bancorp reported a net loss of $(22.9) million, or $(0.49) per diluted share, for the quarter ended June 30, 2026, versus net income of $26.4 million a year earlier. Adjusted net income was $21.0 million, or $0.45 per diluted share.

Results reflect the April 1, 2026 completion of the First Foundation acquisition, which added $11.2 billion of total assets, including $6.0 billion of net loans and $8.8 billion of deposits, after purchase accounting. Net interest income rose to $143.2 million, but net interest margin compressed to 3.58% as the acquired balance sheet carried higher funding costs.

Credit costs increased sharply: the provision for credit losses was $40.4 million and net charge-offs were $42.4 million, largely tied to two commercial and industrial loans. Noninterest expense climbed to $171.7 million, including $57.6 million of merger-related costs. Capital ratios remained above well-capitalized thresholds, with a common equity tier 1 ratio of 11.95% and total assets of $15.7 billion. The board also authorized a share repurchase program of up to $150.0 million through June 30, 2027.

Positive

Completed First Foundation acquisition, adding $11.2 billion of total assets, $6.0 billion of net loans and $8.8 billion of deposits, and expanding the franchise in attractive markets.
Regulatory capital remained high after the merger, with a common equity tier 1 ratio of 11.95% and total risk-based capital of 14.13%, supporting future growth and the new buyback.
Board authorized a $150.0 million share repurchase program through June 30, 2027, giving flexibility to return capital via open-market or privately negotiated transactions.

Negative

Second quarter 2026 showed a net loss of $(22.9) million, or $(0.49) per diluted share, versus net income of $26.4 million and $0.93 per diluted share a year earlier.
Provision for credit losses rose to $40.4 million with net charge-offs of $42.4 million and a net charge-off ratio of 1.45%, driven mainly by two commercial and industrial loans.
Noninterest expense jumped to $171.7 million, including $57.6 million of merger-related expenses, pushing the reported efficiency ratio to a very high 93.25%.

Filing Explained

Completed balance-sheet repositioning reduced selected assets and funding, while the $150 million buyback remains an uncommitted authorization through June 30, 2027.

This Form 8-K reports FirstSun Capital Bancorp’s second-quarter results and other material events; the disclosed balance-sheet repositioning is complete, while the repurchase program remains authorized rather than executed.

The completed repositioning liquidated $1.2 billion of cash, $1.4 billion of securities, and $1.3 billion of loans, with the proceeds and other cash used to reduce $2.5 billion of deposits and $1.4 billion of borrowings.

The board separately authorized up to $150.0 million of common-stock repurchases through June 30, 2027, with timing, pricing, and amount left to management.

That $150.0 million is a ceiling and does not obligate FirstSun to buy shares; the filing therefore establishes capacity, not a completed reduction in common shares.

The authorization may be modified, suspended, or discontinued without prior notice, making June 30, 2027 the stated end date for the current authorization rather than a commitment to use it.

net interest margin financial

"Net interest margin decreased 67 basis points to 3.58% compared to the prior quarter"

Net interest margin measures how much a bank earns from lending and investing compared with what it pays for funding, expressed as a percentage of its interest-earning assets. Think of it like a grocery store’s markup: it shows the gap between buying cost and selling price per dollar of goods — here, the cost is interest paid and the sale is interest received. Investors watch it because a higher margin usually means a bank is more profitable and better at managing interest rate and credit conditions.

allowance for credit losses financial

"The allowance for credit losses as a percentage of loans outstanding was 1.50% at June 30, 2026"

Allowance for credit losses is a reserve set aside by a financial institution to cover potential losses from borrowers who may not repay their loans. It acts like a safety net, helping the institution prepare for loans that might turn sour. For investors, it signals how cautious the institution is about the quality of its loans and potential risks to its financial health.

nonperforming assets financial

"The ratio of nonperforming assets to total assets was 1.32% at June 30, 2026"

Nonperforming assets are loans or investments that are not generating expected payments or returns because the borrower has fallen behind on payments or the investment has lost value. They matter to investors because a high level of nonperforming assets can indicate financial trouble for a bank or institution, potentially affecting its stability and profitability.

common equity tier 1 risk-based capital ratio financial

"common equity tier 1 risk-based capital ratio was 11.95% as of June 30, 2026"

A measure of a bank’s core capital — mainly common shares and retained earnings — divided by its assets after those assets are adjusted for how risky they are. Think of it like a household emergency fund sized against the value and riskiness of what you own: the larger the cushion, the better the bank can absorb losses. Investors use it to judge a bank’s financial strength, safety, and regulatory soundness, which affects dividends, lending capacity and the chance of government intervention.

efficiency ratio financial

"The efficiency ratio for the second quarter of 2026 was 93.25% compared to 68.52% for the prior quarter"

A measure of how much a company spends to produce each dollar of revenue, usually shown as operating expenses divided by revenue and expressed as a percentage. Think of it as a household’s budget: a lower percentage means more of each dollar earned stays as profit, while a higher number means costs are eating into returns. Investors use it to judge cost control and compare how efficiently companies turn revenue into earnings, especially in banks and financial firms.

Board of Directors Authorizes $150 Million Share Repurchase Program

•Completed remaining merger-related balance sheet repositioning strategy of $3.9 billion comprised of $1.2 billion in cash, $1.4 billion in securities, $1.3 billion in loans, $2.5 billion in deposits, and $1.4 billion in borrowings

•Net interest margin of 3.58%

•22.2% noninterest income to total revenue1

Denver, Colorado – July 27, 2026 – FirstSun Capital Bancorp (“FirstSun”) (NASDAQ: FSUN) reported net loss of $(22.9) million for the second quarter of 2026 compared to net income of $26.4 million for the second quarter of 2025. Earnings per diluted share were $(0.49) for the second quarter of 2026 compared to $0.93 for the second quarter of 2025. Adjusted net income, a non-GAAP financial measure, was $21.0 million or $0.45 per diluted share for the second quarter of 2026 compared to $26.6 million or $0.94 per diluted share for the second quarter of 2025.

On April 1, 2026, we completed our merger with First Foundation and its results of operations are included in our consolidated financial results since the date of acquisition. Therefore, our second quarter and first half of 2026 results reflect increased levels of average balances, net interest income, and expenses compared to our prior quarter and first half of 2025. After purchase accounting adjustments, the acquisition added $11.2 billion of total assets, including $6.0 billion of net loans, as well as $10.5 billion of total liabilities, primarily consisting of $8.8 billion in deposits. We recorded preliminary goodwill of $9.1 million and core deposit intangibles and other intangibles of $90.2 million related to the acquisition. During the second quarter of 2026, we incurred $57.6 million in merger related expenses.

During the second quarter of 2026, we completed our previously announced balance sheet repositioning strategy, involving the sale or run-off of select First Foundation loans and securities and using proceeds from such sales and paydowns as well as other available cash and equivalents to reduce higher-cost funding sources. Our balance sheet repositioning strategy was designed to strengthen our capital position, enhance our credit profile, improve our liquidity, and support a more diversified, relationship-focused business model. Our balance sheet repositioning strategy resulted in the liquidation of assets, namely $1.2 billion in cash, $1.4 billion in securities, $1.3 billion in loans, the proceeds of which were used to reduce liabilities, namely $2.5 billion in deposits, and $1.4 billion in borrowings.

Neal Arnold, FirstSun’s Chief Executive Officer and President, commented, “The completion of the First Foundation acquisition in the second quarter marked a transformational milestone for our company. We have accelerated our growth strategy and expanded our footprint across some of the most dynamic markets in the country. In the second quarter, we also successfully completed the repositioning strategy and reduced the risk profile of the balance sheet we acquired. We believe the franchise is stronger, with less concentration risk, less liquidity risk, less interest rate sensitivity, and a stronger capital profile as a result of the repositioning actions. While we experienced a decline in our financial results this quarter due to two large loan charge-offs and the merger and integration expenses

1 Total revenue is net interest income plus noninterest income.

we incurred in conjunction with completing the First Foundation acquisition, we believe our core business remains strong and we believe we are well positioned for future success.

“I want to thank all of our teammates for their diligence, professionalism and commitment to the hard work of integrating the businesses and continuing to serve our great clients and communities. We remain very excited about the growth opportunities across all of our markets as we continue building a premier regional bank.”

Share Repurchase Program

Our board of directors has authorized a share repurchase program to purchase up to $150.0 million of FirstSun’s common stock in open market transactions or privately negotiated transactions, including pursuant to a trading plan in accordance with Rule 10b5-1 and/or Rule 10b-18 under the Securities Exchange Act of 1934, as amended. The timing, pricing, and amount of any repurchases under the repurchase program will be determined by our management at its discretion based on a variety of factors, including, but not limited to, trading volume and market price of our common stock, corporate considerations, our financial performance, alternative uses for capital, general market and economic conditions, legal and regulatory requirements, and other factors. The repurchase program is authorized through June 30, 2027, although it may be modified, discontinued, or suspended at any time without prior notice. The repurchase program does not obligate FirstSun to purchase any shares.

Second Quarter 2026 Results

Net loss totaled $(22.9) million, or $(0.49) per diluted share, for the second quarter of 2026, compared to $21.6 million, or $0.76 per diluted share, for the prior quarter. Adjusted net income, a non-GAAP financial measure, totaled $21.0 million, or $0.45 per diluted share, for the second quarter of 2026, compared to $23.7 million, or $0.84 per diluted share, for the prior quarter.

Return on average total assets was (0.54)% for the second quarter of 2026, compared to 1.04% for the prior quarter, and return on average stockholders’ equity was (4.92)% for the second quarter of 2026, compared to 7.47% for the prior quarter. Adjusted return on average total assets and adjusted return on average stockholders’ equity, each a non-GAAP financial measure, were 0.50% and 4.52% respectively for the second quarter of 2026 compared to 1.14% and 8.20% respectively for the prior quarter.

Net Interest Income and Net Interest Margin

Net interest income totaled $143.2 million for the second quarter of 2026, an increase of $60.4 million compared to the prior quarter. Our net interest margin decreased 67 basis points to 3.58% compared to the prior quarter.

Average loans, including loans held-for-sale, increased by $5.8 billion in the second quarter of 2026, compared to the prior quarter, due primarily to loans acquired from First Foundation. Loan yield decreased by 20 basis points to 6.16% in the second quarter of 2026, compared to the prior quarter, reflecting a change in portfolio mix resulting from the addition of lower-yielding primarily public finance and multifamily loans acquired from First Foundation. Average investment securities increased by $1.6 billion in the second quarter of 2026, compared to the prior quarter, due primarily to securities acquired from First Foundation. Investment securities yield increased by 150 basis points to 4.80% in the second quarter of 2026, compared to the prior quarter, primarily reflecting a change in portfolio mix resulting from the addition of higher-yielding fixed and floating investment securities acquired from First Foundation. Average interest-bearing cash and other assets increased by $700.9 million in the second quarter of 2026, compared to the prior quarter. Interest-bearing cash and other assets yield decreased by 16 basis points to 3.20% in the second quarter of 2026, compared to the prior quarter, primarily reflecting a change in the composition of interest-bearing cash and other assets resulting from the First Foundation acquisition.

Average interest-bearing deposits increased $6.4 billion in the second quarter of 2026, compared to the prior quarter, due primarily to deposits assumed from First Foundation. Total cost of interest-bearing deposits increased by 31 basis points to 2.77% in the second quarter of 2026, compared to the prior quarter, primarily reflecting the addition of higher-cost, non-core deposits acquired from First Foundation.

Asset Quality and Provision for Credit Losses

The provision for credit losses increased $32.2 million to $40.4 million for the second quarter of 2026, compared to the prior quarter, primarily related to the downgrades and write-downs of two C&I lending relationships.

Net charge-offs for the second quarter of 2026 were $42.4 million resulting in an annualized ratio of net charge-offs to average loans of 1.45%, compared to net charge-offs of $10.6 million, or an annualized ratio of net charge-offs to average loans of 0.63% for the prior quarter. The increase in charge-offs for the second quarter of 2026 was primarily related to two C&I loans. The first is an asset-based loan to a materials distributor with an outstanding principal balance of approximately $23.6 million at June 30, 2026. Based on current information, we believe the borrower made fraudulent misrepresentations about its accounts receivable, collateral and historical financial statements and, as a result, in the second quarter of 2026, we recognized an approximate $22.0 million charge-off on this loan, or an annualized net charge-off of 0.75%. The second is a loan to a technology company with an outstanding principal balance of approximately $16.0 million at June 30, 2026. Based on recent developments impacting the borrower’s business, including deterioration in the borrower’s financial performance in the second quarter, we recognized a $12.9 million charge-off on this loan in the second quarter of 2026.

In connection with the acquisition of First Foundation, we recorded an initial allowance for credit losses of $92.5 million using the gross up approach, comprised of a $39 million reserve for purchased credit deteriorated loans that exhibited a more-than-insignificant amount of credit deterioration since origination and a $53.5 million reserve on purchased seasoned loans. The allowance for credit losses as a percentage of loans outstanding was 1.50% at June 30, 2026, an increase of 30 basis points from the prior quarter. The ratio of nonperforming assets to total assets was 1.32% at June 30, 2026, compared to 0.82% at March 31, 2026.

Noninterest Income

Noninterest income totaled $40.9 million for the second quarter of 2026, an increase of $13.8 million from the prior quarter. Income from trust and investment advisory fees increased $7.9 million for the second quarter of 2026 from the prior quarter, primarily due to higher assets under management associated with the acquisition of First Foundation. Income from mortgage banking services increased $1.6 million for the second quarter of 2026 from the prior quarter, primarily due to an increase in loan originations sold and corresponding capitalized servicing rights as well as slower balance runoff in the servicing portfolio. Other noninterest income increased $3.3 million for the second quarter of 2026 from the prior quarter, primarily due to an increase in the fair value of investments related to our deferred compensation plan partially offset by a write-down of an OREO property.

Noninterest income as a percentage of total revenue2 was 22.2% for the second quarter of 2026, a decrease of 2.5% from the prior quarter.

Noninterest Expense

Noninterest expense totaled $171.7 million for the second quarter of 2026, an increase of $96.4 million from the prior quarter. Merger related expenses increased $54.9 million in the second quarter of 2026 from the prior quarter. Salary and employee benefits increased $21.4 million in the second quarter of 2026 from the prior quarter, primarily due to an increase in headcount associated with the acquisition of First Foundation. Other noninterest expense increased $8.1 million in the second quarter of 2026 from the prior quarter, primarily due to higher data processing and FDIC insurance expenses associated with our increased scale following the acquisition of First Foundation.

The efficiency ratio for the second quarter of 2026 was 93.25% compared to 68.52% for the prior quarter. The adjusted efficiency ratio, a non-GAAP financial measure, for the second quarter of 2026 was 61.99% compared to 66.08% for the prior quarter.

Tax Rate

The effective tax rate was 18.3% for the second quarter of 2026, compared to 18.1% for the prior quarter.

2 Total revenue is net interest income plus noninterest income.

Non-GAAP Financial Measures

This press release (including the tables beginning on page 17) contains financial measures determined by methods other than in accordance with accounting principles generally accepted in the United States (“GAAP”). Our management uses these non-GAAP financial measures in their analysis of our performance and the efficiency of our operations. Management believes these non-GAAP measures provide a greater understanding of ongoing operations, enhance comparability of results with prior periods and demonstrate the effects of significant items in the current period. We believe a meaningful analysis of our financial performance requires an understanding of the factors underlying that performance. Our management believes investors may find these non-GAAP financial measures useful. These non-GAAP financial measures, however, should not be viewed as a substitute for financial measures determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Below is a listing of the non-GAAP measures used in this press release:

•Tangible stockholders’ equity to tangible assets;

•Tangible stockholders’ equity to tangible assets, reflecting net unrealized losses on HTM securities, net of tax;

•Tangible book value per share;

•Adjusted net income;

•Adjusted diluted earnings per share;

•Adjusted return on average total assets;

•Adjusted return on average stockholders’ equity;

•Return on average tangible stockholders’ equity;

•Adjusted return on average tangible stockholders’ equity;

•Adjusted total noninterest expense;

•Adjusted efficiency ratio; and

•Fully tax equivalent (“FTE”) net interest income and net interest margin.

•Adjusted loan growth

•Adjusted deposit growth

The tables beginning on page 17 provide a reconciliation of the non-GAAP financial measures contained in this press release to the most comparable GAAP equivalent.

Deposits Classification

Previously, deposit amounts related to certain NOW accounts with limited monthly transaction activity were able to be reclassified to money market accounts to reduce reserve requirements at the Federal Reserve. As there is no longer any impact to reserve requirements across different deposit products, we have discontinued this product reclassification practice and have revised the presentation of those deposits to conform to the current presentation for periods prior to March 31, 2026.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This press release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking statements. Examples of forward-looking statements include, but are not limited to, statements regarding our markets, our merger with First Foundation, including our belief regarding the benefits of the merger and our recently completed balance sheet repositioning on our franchise, the strength of our core business, our ability to drive growth, and that we are well positioned for future success. These statements reflect management’s current expectations and are not guarantees of future performance. Words such as “focus,” “confident,” “may,” “will,” “believe,” “anticipate,” “expect,” “intend,” “opportunity,” “continue,” “should,” “could,” “excited,” “progress” and variations of such words and similar expressions are intended to identify such forward-looking statements. Forward-looking statements are subject to risks, uncertainties and assumptions that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results. Such risks, uncertainties and assumptions, include, among others, the following: changes in interest rates and their related impact on macroeconomic conditions, customer behavior, our funding costs and our loan and securities portfolios; the quality or composition of our loan or investment portfolios and changes therein; failure to maintain our mortgage production flow to secondary markets; the sufficiency of liquidity and changes in our capital position; the inability of our infrastructure initiatives to reduce expenses; increased deposit volatility; potential regulatory developments; U.S. and global trade policies and tensions, including change in, or the imposition of, tariffs and/or trade barriers and the economic impacts, volatility and uncertainty resulting therefrom; ongoing geopolitical conflicts, including hostilities involving Iran and the Middle East, which may contribute to volatility in energy prices, inflation, financial markets, cybersecurity threats, and broader macroeconomic conditions, any of which could adversely affect our borrowers, deposit base, liquidity, capital and results of operation; the possibility that the anticipated benefits of the First Foundation merger, including anticipated cost savings and strategic gains, are not realized when expected or at all; the integration of the businesses and operations of FirstSun and First Foundation may take longer than anticipated or be more costly than anticipated or have unanticipated adverse results relating to the combined company’s business; the diversion of management’s attention from ongoing business operations and opportunities due to the First Foundation merger; other factors, many of which are beyond our control.

We caution readers that the foregoing list of factors is not exclusive, is not necessarily in order of importance and readers should not place undue reliance on any forward-looking statements. Additional information concerning additional factors that could materially affect the forward-looking statements in this press release can be found in the cautionary language included under the headings “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in FirstSun’s Annual Report on Form 10-K for the year ended December 31, 2025 and other documents subsequently filed by FirstSun with the SEC. Further, any forward-looking statement speaks only as of the date on which it is made and we do not intend to and disclaim any obligation to update or revise any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except as required by law.

2Q2026 Earnings Presentation July 27, 2026 FirstSun Capital Bancorp NASDAQ: FSUN

FirstSun Capital Bancorp | 2 Disclaimers Forward-Looking Statements This presentation contains forward-looking information and statements by FirstSun Capital Bancorp (“FirstSun” or the “Company”) within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are generally identifiable by the use of words such as “believe”, “expect”, “anticipate”, “plan”, “project”, “intend”, “estimate”, “may”, “will”, “would”, “could”, “should”, “assume”, “assumptions”, “view”, “continue”, “opportunity”, “strategic emphasis,” “seek to,” and “outlook” or other similar expressions, and in this presentation include statements regarding our strategy, our merger with First Foundation Inc. (“First Foundation” or “FFWM”), our outlook regarding our loan portfolio, deposit mix, net interest income, noninterest income, noninterest expense, asset quality, liquidity and capital priorities, as well as statements on the slide entitled “2026 Full Year Financial Outlook,” including our full year 2026 outlook, Q4 2026 outlook, key assumptions and further expectations. Forward-looking statements are subject to risks, uncertainties and assumptions that are difficult to predict with regard to timing, extent, likelihood and degree of occurrence, which could cause actual results to differ materially from anticipated results. Such risks, uncertainties and assumptions, include, among others, the following: changes in interest rates and their related impact on macroeconomic conditions, customer behavior, our funding costs and our loan and securities portfolios; the quality or composition of our loan or investment portfolios and changes therein; failure to maintain our mortgage production flow to secondary markets; the sufficiency of liquidity and changes in our capital position; the inability of our infrastructure initiatives to reduce expenses; increased deposit volatility; potential regulatory developments; U.S. and global trade policies and tensions, including change in, or the imposition of, tariffs and/or trade barriers and the economic impacts, volatility and uncertainty resulting therefrom; ongoing geopolitical conflicts, including hostilities involving Iran and the Middle East, which may contribute to volatility in energy prices, inflation, financial markets, cybersecurity threats, and broader macroeconomic conditions, any of which could adversely affect our borrowers, deposit base, liquidity, capital and results of operation; the possibility that the anticipated benefits of the First Foundation merger, including anticipated cost savings and strategic gains, are not realized when expected or at all; the integration of the businesses and operations of FirstSun and First Foundation may take longer than anticipated or be more costly than anticipated or have unanticipated adverse results relating to the combined company’s business; the diversion of management’s attention from ongoing business operations and opportunities due to the First Foundation merger; other factors, many of which are beyond our control. We caution readers that the foregoing list of factors is not exclusive, is not necessarily in order of importance and readers should not place undue reliance on any forward-looking statements. Additional information concerning additional factors that could materially affect the forward-looking statements in this presentation can be found in the cautionary language included under the headings “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in FirstSun’s Annual Report on Form 10-K for the year ended December 31, 2025 and other documents subsequently filed by FirstSun with the SEC. Further, any forward-looking statement speaks only as of the date on which it is made and we do not intend to and disclaim any obligation to update or revise any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except as required by law. 2026 Full Year and Q4 2026 Outlook and 2027 Further Expectations - Basis and Limitations Our 2026 Full Year and Q4 2026 Financial Outlook and 2027 Further Expectations reflect management’s current expectations regarding certain financial and operating metrics and related key assumptions and further expectations as of July 27, 2026. Unless otherwise noted, outlook metrics represent full-year expectations and includes nine months impact of the First Foundation merger that closed on April 1, 2026. The outlook includes preliminary estimates of acquisition-related purchase accounting adjustments with respect to the First Foundation merger, which are subject to change. The outlook and further expectations are provided for convenience and should not be regarded as a guarantee of future results. Actual results, conditions or outcomes may differ materially. See “Forward-Looking Statements” in the above heading. We undertake no obligation to update or affirm the outlook or further expectations, except as required by law. Forward-looking non-GAAP measures appearing in the 2026 Full Year and Q4 2026 Financial Outlook should be read together with “Use of Non-GAAP Measures.”

FirstSun Capital Bancorp | 3 Disclaimers (cont’d) Use of Non-GAAP Measures This presentation includes certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States (“GAAP”). These non-GAAP financial measures include certain operating performance measures that exclude merger-related and other charges that are not considered part of the Company’s recurring operations. The Company’s management uses these non-GAAP financial measures in their analysis of the Company’s performance and the efficiency of its operations. Management believes these non-GAAP measures provide a greater understanding of the Company’s ongoing operations, enhance comparability of results with prior periods and demonstrate the effects of significant items in the current period. The Company believes a meaningful analysis of its financial performance requires an understanding of the factors underlying that performance. The Company’s management believes investors may find these non-GAAP financial measures useful and that these non-GAAP financial measures provide useful supplemental information for evaluating the Company’s performance trends. Further, the Company’s management uses these measures in managing and evaluating the Company’s business and intends to refer to them in discussions about the Company’s operations and performance. These non-GAAP financial measures, however, should not be viewed as a substitute for financial measures determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies These measures should be viewed in addition to, and not as an alternative to, or substitute for, measures that are determined in accordance with GAAP. To the extent applicable, reconciliations of these non-GAAP measures to the most directly comparable GAAP measure are included in the Appendix to this presentation. Deposits Classification Previously, deposit amounts related to certain NOW accounts with limited monthly transaction activity were able to be reclassified to money market accounts to reduce reserve requirements at the Federal Reserve. As there is no longer any impact to reserve requirements across different deposit products, we have discontinued this product reclassification practice and have revised the presentation of those deposits to conform to the current presentation for periods prior to March 31, 2026. Market, Industry and Statistical Data Certain market and industry data used in this presentation are based on third-party sources, publicly available information and internal estimates. We believe such information to be reliable, but we have not independently verified it and make no representation as to its accuracy or completeness.

The effect on net interest income and economic value of equity over a 12-month time horizon due to hypothetical changes in market interest rates is presented in the charts above. In this interest rate shock simulation, as of the periods presented, interest rates have been adjusted by instantaneous parallel changes rather than in a ramp simulation, which applies interest rate changes over time. All rates, short-term and long-term, are changed by the same amount (e.g., plus or minus 100 basis points) resulting in the shape of the yield curve remaining unchanged. Simulation results are not intended to forecast actual results due to the effect of changes in interest rates.

See "Disclaimers" beginning on slide 2. 2026/2027 expectations assume no material changes to current regional, national and international macroeconomic environment. 2 Total revenue is net interest income plus noninterest income. 3Adjusted efficiency ratio is a forward-looking non-GAAP financial measure that exclude merger related expenses. We are unable to provide a reconciliation of forward-looking non-GAAP financial measures because we are unable to provide, without unreasonable effort, a meaningful or accurate calculation or estimation of amounts that would be necessary for the reconciliation due to the complexity and inherent difficulty in forecasting and quantifying future amounts or when they may occur. The unavailable information could be material to future GAAP results, and we cannot quantify its probable significance because such items are inherently uncertain and depend on future events. Key Assumptions: • The outlook includes acquisition-related purchase accounting adjustments with respect to the First Foundation acquisition, which are subject to change • Net loan growth inclusive of up to an estimated $100M and $285M in Multifamily loan re-pricing runoff in 2H 2026 and 2027, respectively • Contractual estimated pre-tax net accretion of $70-$75M for full year of 2026 and $85-90M for 2027 • Share repurchases of an aggregate of approximately $150M expected to occur over the next four quarters • CET 1 ratio expected to be in the 11.75-12% range • Loan to deposit ratio in the mid to high 80s range • Macro rates remain stable Further Expectations: • 2027 loan and deposit growth expected to be in the mid single digits. • Expect further NIM improvement into 1Q 2027, moving into the high 3.80s range • Expect further realization of acquisition-related cost savings through 2H 2026 to result in efficiency ratio in 1Q 2027 in high-50s to low-60s range Key Assumptions and Further Expectations
