FIRSTSUN CAPITAL BANCORP

($ in thousands, except share and per share amounts)

NOTE 1 -Organization and Basis of Presentation

Nature of Operations -The consolidated financial statements include the accounts of FirstSun Capital Bancorp (“FirstSun” or “Parent Company”) and its wholly-owned subsidiaries, Sunflower Bank, N.A. (the “Bank”), Sunflower Wealth Advisors LLC, and FEIF Capital Partners, LLC, and have been prepared using U.S. generally accepted accounting principles (“GAAP”) and prevailing practices in the banking industry. All significant intercompany balances and transactions have been eliminated. These entities are collectively referred to as “our”, “us”, “we”, or “the Company”.

Basis of Presentation -The consolidated financial statements in this Quarterly Report on Form 10-Q have been prepared in accordance with GAAP for interim financial information, but do not include all of the information and footnotes required by GAAP for a full year presentation and certain disclosures have been condensed or omitted in accordance with rules and regulations of the SEC. These interim financial statements are unaudited, and include, in our opinion, all adjustments necessary for a fair statement of the results for the periods indicated, which are not necessarily indicative of results which may be expected for the full year. These unaudited consolidated financial statements and notes should be read in conjunction with FirstSun’s audited consolidated financial statements and footnotes thereto for the year ended December 31, 2025, included in our 2025 Annual Report.

Use of Estimates -The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

These estimates are based on historical experience and on various assumptions about the future that are believed to be reasonable based on all available information. Our reported financial position or results of operations may be materially different under changed conditions or when using different estimates and assumptions, particularly with respect to critical accounting policies. In the event that estimates or assumptions prove to differ from actual results, adjustments are made in subsequent periods to reflect more current information.

Reclassifications -Some items in the prior year financial statements were reclassified to conform to the current presentation. 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. Reclassifications had no effect on prior years net income or stockholders’ equity.

Accounting Pronouncements Recently Adopted -As an “emerging growth company” under Section 107 of the JOBS Act, we can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Therefore, we can delay the adoption of certain accounting standards until those standards would otherwise apply to non-public business entities. We intend to take advantage of the benefits of this extended transition period for an “emerging growth company” for as long as it is available to us. For standards that we have delayed adoption, we may lack comparability to other companies who have adopted such standards.

ASU No. 2025-05,“Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets.” ASU 2025-05 provides all entities, when developing reasonable and supportable forecasts as part of estimating expected credit losses on current accounts receivable and/or current contract assets arising from transactions under ASC Topic 606 - Revenue from Contracts with Customers, a practical expedient whereby entities can assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. ASU 2025-05 became effective for us in 2026 and did not have a significant impact on our financial statements.

Recent Accounting Pronouncements Not Yet Adopted - ASU No. 2024-03,“Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires disaggregated disclosure of income statement expenses for public business entities. ASU 2024-03 requires new financial statement disclosures in tabular format, disaggregating information about prescribed categories underlying any relevant income statement expense caption. The prescribed categories include, among other things, employee compensation, depreciation, and intangible asset amortization. Additionally, entities must disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. ASU 2024-03 will be effective for us, on a prospective basis, for annual periods beginning in 2027, and interim periods within fiscal years beginning in 2028, though early adoption and retrospective application is permitted. ASU 2024-03 is not expected to have a significant impact on our financial statements.

ASU No. 2025-06,“Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software.” ASU 2025-06 simplifies and modernizes the accounting for internal-use software by removing prescriptive project stage guidance and introducing a new capitalization threshold. Under the revised standard, software development costs are capitalized when management authorizes and commits funding for the project and it is probable the software will be completed and used as intended. ASU 2025-06 will be effective in 2028 and is not expected to have a significant impact on our financial statements.

ASU 2025‑08,“Financial Instruments - Credit Losses (Topic 326): Purchased Loans.” ASU 2025-08 expands the scope of the “gross‑up” method, formerly applicable only to purchased credit‑deteriorated (“PCD”) assets, to include acquired non‑PCD loans that meet certain criteria, now referred to as “purchased seasoned loans” (PSLs). Under this model, an allowance for expected credit losses is recognized at acquisition, offsetting the loan’s amortized cost basis, thereby eliminating the day-one credit‑loss expense previously required for non‑PCD assets. PSLs are defined as non‑PCD loans acquired either (i) through a business combination, or (ii) purchased more than 90 days after origination when the acquirer was not involved in origination. ASU 2025-08 will be effective for us, on a prospective basis for loans acquired on or after the adoption date, for interim and annual reporting periods beginning in 2027, though early adoption is permitted. We plan to early adopt on April 1, 2026 in conjunction with our acquisition of First Foundation Inc. We are not currently able to estimate the impact adoption will have on our financial statements, as our purchase accounting estimates are not yet complete.

ASU 2025‑09,“Derivatives and Hedging (Topic 815): Hedge Accounting Improvements.” ASU 2025-09 amends ASC 815 to align hedge accounting more closely with an entity’s economic risk management practices. Key amendments include (i) to allow designating a variable price component of a nonfinancial forecasted purchase or sale as the hedged risk, (ii) to allow grouping individual forecasted transactions with similar (not identical) risk exposures, (iii) a new model for hedging forecasted interest on variable-rate debt, enabling changes in index or tenor without dedesignation, subject to simplifying assumptions, and (iv) additional clarifications related to hedge accounting of nonfinancial components, net written options, and dual-hedge strategies. ASU 2025-09 will be effective for us beginning in 2027, though early adoption is permitted. ASU 2025-09 is not expected to have a significant impact on our financial statements.

ASU 2025‑11,“Interim Reporting (Topic 270): Narrow‑Scope Improvements.” ASU 2025-11 clarifies and enhances guidance under ASC 270 on interim financial reporting by (i) clarifying the scope of ASC 270 such that it now explicitly applies only to entities that issue complete interim financial statements and related notes under U.S. GAAP, (ii) establishing clear guidance on the form of interim statements and notes, incorporating a comprehensive list of required interim disclosures drawn from across the ASC, and (iii) introducing a requirement to disclose material events and changes occurring after the end of the last annual period that could impact interim results. ASU 2025-11 will be effective for us for interim periods beginning in 2028, though early adoption is permitted. ASU 2025-11 is not expected to have a significant impact on our financial statements.

NOTE 2 -Acquisition of First Foundation Inc.

On April 1, 2026, FirstSun completed its previously announced acquisition of First Foundation Inc. (“First Foundation”), pursuant to the Agreement and Plan of Merger dated October 27, 2025, by and between FirstSun and First Foundation, as amended (the “Merger Agreement”). At the effective time of the merger (the “Effective Time”), First Foundation merged with and into FirstSun, with FirstSun surviving the merger. Immediately following the merger, First Foundation Bank, a California-chartered banking corporation and wholly owned subsidiary of First Foundation, merged with and into the Bank, with the Bank continuing as the surviving bank. Because the merger closed after quarter-end, the historical consolidated financial results of First Foundation are not included in FirstSun’s consolidated financial results for the quarter ended March 31, 2026.

Under the terms of the Merger Agreement, at the Effective Time, each share of First Foundation common stock issued and outstanding immediately prior to the Effective Time (other than certain excluded shares specified in the Merger Agreement) became entitled to receive 0.16083 of a share of FirstSun common stock (the “exchange ratio”), with cash paid in lieu of any fractional shares. In addition, at the Effective Time, each then-outstanding share of First Foundation Series A Noncumulative Convertible Preferred Stock (the “Series A stock”) and Series C Non-Voting Common Equity Equivalent Stock (the “Series C stock” and together with the Series A stock, the “First Foundation Preferred Stock”) was converted into the right to receive 0.16083 of a share of FirstSun common stock for each share of First Foundation common stock into which the First Foundation Preferred Stock was convertible into immediately prior to the Effective Time, subject to certain exceptions. In connection with the merger, we issued approximately 16.1 million voting shares and 2.6 million non-voting shares of FirstSun common stock to stockholders of First Foundation, with the stock consideration valued at approximately $682.8 million as of March 31, 2026, the last trading day before consummation of the acquisition. In addition, we made an aggregate cash payment of $17.5 million to First Foundation warrant holders and assumed First Foundation non-vested restricted stock awards with an estimated pre-combination vesting value of $3.3 million.

NOTE 3 -Securities

The amortized cost, gross unrealized gains and losses, and fair values of available-for-sale and held-to-maturity debt securities by type follows as of:

There wasno allowance for credit losses related to our investment securities as of March 31, 2026 and December 31, 2025.

As of March 31, 2026 and December 31, 2025, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders’ equity.

Fair value and unrealized losses on debt securities by type and length of time in a continuous unrealized loss position without an allowance for credit losses were as follows:

We do not consider the unrealized losses to be credit-related, as these unrealized losses primarily relate to changes in interest rates and market spreads subsequent to purchase. We do not have plans to sell any of the available-for-sale debt securities with unrealized losses as of March 31, 2026, and we believe it is more likely than not that we would not be required to sell such available-for-sale debt securities before recovery of their amortized cost.

We continue to monitor unrealized loss positions for potential credit impairments. During the three months ended March 31, 2026 and 2025, there were no credit impairments related to our investment securities.

The amortized cost and fair value of our debt securities by contractual maturity as of March 31, 2026 are summarized in the following table. Maturities are based on the final contractual payment dates and do not reflect the impact of prepayments or earlier redemptions that may occur.

Securities with a carrying value of $359,625 and $361,877 were pledged to secure public deposits, securities sold under agreements to repurchase, and borrowed funds at March 31, 2026 and December 31, 2025, respectively.

Available-for-sale debt securities with a carrying value of $38,894 and $39,114 were designated in fair value hedges at March 31, 2026 and December 31, 2025, respectively. See Note 6 - Derivative Financial Instruments for further information.

There wereno proceeds from sales and calls of securities for the three months ended March 31, 2026. There were $946 proceeds from sales and calls of securities for the three months ended March 31, 2025.

NOTE 4 -Loans

Loans held-for-investment by portfolio type consist of the following as of:

As of March 31, 2026 and December 31, 2025, we had net deferred fees, costs, premiums and discounts of $17,543 and $13,538, respectively, on our loan portfolio.

Accrued interest receivable on loans totaled $30,909 and $30,031 at March 31, 2026 and December 31, 2025, respectively, and is included in accrued interest receivable in the accompanying consolidated balance sheets.

The following table presents the activity in the allowance for credit losses by portfolio type for the three months ended March 31,:

We determine the allowance for credit losses estimate on at least a quarterly basis.

As of March 31, 2026 and December 31, 2025, we had an allowance for credit losses on unfunded commitments of $959 and $1,209, respectively, included in accrued expenses and other liabilities within the consolidated balance sheets. For the three months ended March 31, 2026 and 2025 we recorded a benefit for credit losses on unfunded commitments of $250 and $400, respectively.

The following table presents our loan portfolio aging analysis as of:

Interest income recorded on nonperforming loans was not material for the three months ended March 31, 2026 and 2025.

Credit risk monitoring and management is a continuous process to manage the quality of the loan portfolio. We segment loans into risk categories based on relevant borrower risk profile information, including the ability of borrowers to service their debt based on current financial information, historical payment experience, credit documentation, public information and current economic trends among other factors. The risk rating system is used as a tool to analyze and monitor movements in loan portfolio quality.

Risk ratings meeting an internally specified exposure threshold are updated annually, or more frequently upon the occurrence of a circumstance that affects the credit risk of the loan. We use the following definitions for risk ratings:

Pass – Loans classified as Pass have a well-defined primary source of repayment, an acceptable financial position profile (including capitalization), profitability and minimal operating risk.

Pass/Watch – Pass/Watch loans require close attention by bank management and enhanced monitoring due to quantitative or qualitative concerns linked to adverse trends or near-term uncertainty. A covenant default or other type of requirement shortfall may have arisen subsequent to a loan's booking or borrower now shows signs of weakness in the overall base of confirmable financial resources available to repay the loan. However, overall financial capacity & performance are considered sufficient to support an expectation of continued payment performance and / or mitigating factors exist that are expected to limit the risk of near term default and loss.

Special Mention – Special Mention loans have identified potential weaknesses that are of sufficient materiality to require management’s (persistent) close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or in the bank's credit position under normal business operations. Special Mention loans contain greater than acceptable risk to warrant increases in credit exposure and are thus considered “criticized”, non-pass rated credits. They may contain weaknesses (that have arisen due to deteriorating conditions since origination) and / or underwriting exceptions that are not currently offset by mitigating factors. However, these weaknesses, while sufficient to constitute significantly elevated credit risk, are not sufficient to support a conclusion that the liquidation of the debt is in significant jeopardy.

Substandard - Accruing – Substandard - Accruing loans are inadequately protected by the current sound net worth and paying capacity of the obligor(s). Loans classified as Substandard - Accruing possess one or more well-defined weaknesses that are expected to jeopardize their liquidation but the weaknesses have not progressed to a point where recent late payments on the loan have become more than 90 days past due. These loans are characterized by the distinct possibility that the bank may sustain up to a moderate but not significant level of loss if such weaknesses are not corrected. Losses for Substandard - Accruing loans are moderated by the lower likelihood of ultimate default and the existence of relatively favorable secondary repayment protection. These loans are considered “nonperforming”.

Substandard - Nonaccrual – Substandard - Nonaccrual loans are inadequately protected by the current sound net worth and paying capacity of the obligor or the collateral pledged, if any. Loans classified as Substandard - Nonaccrual possess material, well-defined weaknesses that are expected to jeopardize their liquidation and have progressed to a point where consistently late payments on the loan have become more than 90 or more days past due. These loans are characterized by the distinct possibility that the bank may sustain a material level of loss if such weaknesses are not corrected. Losses for Substandard - Nonaccrual loans are prone to being elevated based on the strong likelihood of the loan remaining in payment default and an undesirable level of secondary repayment protection. These loans are considered “nonperforming”.

Doubtful – Loans classified as Doubtful possess all of the weaknesses inherent in loans classified as Substandard - Nonaccrual with the added characteristic that the weaknesses make collection or liquidation in full highly questionable or improbable based on currently existing facts, conditions and values. A high probability of substantial loss or possible total loss exists. Loans rated as doubtful are not rated as loss because certain events may occur that could salvage at least a portion of the debt. These events include injections of capital, additions of pledged collateral or possible mezzanine debt refinancing options. However, without the occurrence of such events, total loss may be possible. No definite repayment schedule exists for these loans. The Doubtful grade is a temporary grade. If a near term recovery of a portion of the loan balance is indeterminable or unlikely to occur, the remaining balance of the loan should be written off and possible future recoveries may partially offset the full write-off of the loan. These loans are considered “nonperforming”.

Loss – Loans classified as Loss are defaulted loans with limited or immaterial recovery prospects. No loan that has not yet defaulted should be classified at this grade level. This rating level tends to be very short lived as the full balance of the loan tends to be fully written off nearly immediately after a change to this rating level. These loans are considered “nonperforming”.

The following table presents the amortized cost by segment of loans by risk category and origination date as of March 31, 2026 and gross charge-offs by origination date for the three months ended March 31, 2026:

The following table presents the amortized cost by segment of loans by risk category and origination date as of December 31, 2025 and gross charge-offs by origination date for the year ended December 31, 2025:

The following table presents information about collateral dependent loans that were individually evaluated for purposes of determining the ACL as of:

The allowance related to collateral dependent loans reported in the tables above includes qualitative adjustments applied to the loan portfolio that consider possible changes in circumstances that could ultimately impact credit losses and might not be reflected in historical data or forecasted data incorporated in the quantitative models.

Loan Modifications Made to Borrowers Experiencing Financial Difficulty:

The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon origination. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. We use a PD/LGD model to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made at the time of a modification. The loan modifications in the table below did not significantly impact our determination of the allowance for credit losses on loans during the three months ended March 31, 2026.

Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses, a change to the allowance for credit losses is generally not recorded upon modification. Occasionally, we modify loans by providing principal forgiveness that is deemed to be uncollectible; therefore, that portion of the loan is written-off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the allowance for credit losses. Additionally, we may allow a loan to go interest only for a specified period of time.

The following tables present loan modifications for borrowers experiencing financial difficulty, segregated by modification type, regardless of whether such modifications resulted in a new loan.

For the three months ended March 31,:

There were commitments to lend additional funds to these borrowers of $3,416 at March 31, 2026.

We closely monitor the performance of loan modifications made to borrowers experiencing financial difficulty to understand the effectiveness of the modification efforts. The following table depicts the performance of loan modifications made to borrowers experiencing financial difficulty that have been modified in the preceding 12 months:

NOTE 5 -Mortgage Servicing Rights

We have investments in mortgage servicing rights (“MSRs”) that result from the sale of loans to the secondary market for which we retain the servicing. We account for these MSRs at their fair value.

The unpaid principal loan balance of our servicing portfolio is presented in the following table as of:

The activity of MSRs carried at fair value is as follows:

The following represents the weighted-average key assumptions used to estimate the fair value of MSRs as of:

Total servicing and ancillary fees earned from the mortgage servicing portfolio is presented in the following table:

NOTE 6 -Derivative Financial Instruments

Banking Derivative Financial Instruments:

We use fair value hedges to seek to manage our exposure to changes in the fair value of certain recognized assets attributable to changes in a benchmark interest rate, such as SOFR. The fair value hedges were determined to be effective during all periods presented and we expect the hedges to remain effective during their remaining terms.

Derivatives not designated as hedges are not speculative and result from a service we provide to certain customers. We execute interest rate swaps with banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously offset by derivatives that we execute with a third-party, such that we minimize our net risk exposure resulting from such transactions. As the interest rate derivatives associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

Derivative instruments are measured at fair value and recorded as a component of prepaid expenses and other assets and accrued expenses and other liabilities.

The components of our banking derivative financial instruments consisted of the following as of:

We recorded gains and losses on banking derivative assets and liabilities as follows:

For the three months ended March 31, 2026 and 2025, our banking derivative financial instruments not designated as hedging instruments generated fee income of $577 and $465, respectively.

The carrying amount of hedged loans receivable as of March 31, 2026 and December 31, 2025 was $143,233 and $143,896, respectively. The cumulative amount of fair value hedging adjustment included in the carrying amount of the hedged loans receivable as of March 31, 2026 and December 31, 2025 was $(4,895) and $(4,835), respectively. The fair value hedging adjustment included in other noninterest income for the three months ended March 31, 2026 and 2025 was $(60) and $2,216, respectively.

The carrying amount of hedged available-for-sale debt securities as of March 31, 2026 and December 31, 2025 was $38,894 and $39,114, respectively. The cumulative amount of fair value hedging adjustment included in the amortized cost amount of the hedged available-for-sale debt securities as of March 31, 2026 and December 31, 2025 was $(2,600), and

$(2,443), respectively. The fair value hedging adjustment included in interest income for the three months ended March 31, 2026 and 2025 was $(158) and $1,075, respectively.

Credit-risk-related Contingent Features:

We have agreements with each of our derivative counterparties that contain a provision where if we either default or are capable of being declared in default on any of our indebtedness, then we could also be declared in default on our derivative obligations.

We also have agreements with our derivative counterparties that contain a provision where if we fail to maintain our status as a well-capitalized institution, then our derivative counterparties have the right but not the obligation to terminate existing swaps. As of March 31, 2026 and December 31, 2025, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $14,138 and $15,092, respectively. As of March 31, 2026 and December 31, 2025, we have minimum collateral posting thresholds with our derivative counterparties and have posted collateral of $7,960 and $5,890, respectively. If we had breached any of these provisions at March 31, 2026, we could have been required to settle our obligations under the agreements at their termination value of $14,138.

Mortgage Banking Derivative Financial Instruments:

The components of our mortgage banking derivative financial instruments consisted of the following as of:

We recorded gains and losses on mortgage banking derivative assets and liabilities as follows:

NOTE 7 -Deposits

The composition of our deposits is as follows as of:

The following table summarizes the interest expense incurred on our deposits:

The remaining maturity on certificate of deposit accounts is as follows as of:

NOTE 8 -Debt

FHLB advances

The following is a breakdown of our FHLB advances and other borrowings outstanding as of:

Our FHLB advances are typically considered short-term borrowings with maturities less than one year and are used to manage liquidity as needed. Maturing advances are replaced by drawing on available cash, making additional borrowings or through increased customer deposits. The advances were collateralized by $2,844,319 and $2,761,116 of loans pledged to the FHLB as of March 31, 2026 and December 31, 2025, respectively.

As of March 31, 2026 and December 31, 2025, the Bank had total borrowing capacity with the FHLB that is based on qualified collateral lending values of $1,538,919 and $1,491,095, respectively. Our additional borrowing availability with the FHLB at March 31, 2026 was $1,350,880. These borrowings can be in the form of additional term advances or a line-of-credit.

FRB advances

We also had a $2,181,928 line-of-credit with the FRB. The agreement bears interest at the Fed Funds target rate plus 0.50% and is secured by $2,581,150 of investment securities and loans pledged to the FRB as collateral. No amounts were drawn on the line-of-credit as of March 31, 2026.

Other borrowings

We have lines-of-credit with certain other financial institutions totaling $125,000 as of March 31, 2026. No amounts were drawn on these lines-of-credit at March 31, 2026.

Subordinated Debt

Subordinated Note - 2022

On January 13, 2022, we issued a subordinated note totaling $25,000. The note pays interest at a fixed rate of 3.375% through January 15, 2027 and subsequently, until maturity, pays interest at a floating rate of three month term SOFR plus 2.03%, reset quarterly. Interest is payable on July 15 and January 15 of each year. Such note is due on January 15, 2032. The note is not redeemable within the first five years of issuance, except under certain limited conditions. After five years, we may redeem the note at our discretion. We incurred and capitalized $534 of costs related to the issuance of the subordinated note. The amortization associated with the capitalized issuance costs isnot significant for the periods presented.

Trust preferred securities

We have issued $9,279 in trust preferred securities through a special-purpose trust, New Mexico Banquest Capital Trust I (“NMBCT I”). In addition, we have issued $4,640 in trust preferred securities through a special purpose trust, New Mexico Banquest Capital Trust II (“NMBCT II”, and together with NMBCT I, collectively referred to as “NMBCT Trusts”). Interest is payable quarterly at a rate of three-month term SOFR plus 3.35% (7.31% and 7.91% as of March 31, 2026 and 2025, respectively) for the trust preferred securities issued through NMBCT I and at a rate of three-month term SOFR plus 2.00% (5.93% and 6.59% as of March 31, 2026 and 2025, respectively) for the trust preferred securities issued through NMBCT II.

This subordinated debt of $13,919 was originally recorded at a discount of $4,293. The accretion associated with the fair value discount is not significant for the periods presented.

The Parent Company fully and unconditionally guarantees the obligations of the NMBCT Trusts on a subordinated basis. The trust preferred securities issued through the NMBCT Trusts are mandatorily redeemable upon the maturity of the debentures on December 19, 2032 and November 23, 2034, respectively, and are optionally redeemable, in part or in whole, by the Parent Company at each quarterly interest payment date. The Parent Company owns all of the outstanding common securities of the NMBCT Trusts, which have an aggregate liquidation valuation amount of $419 and is recorded in prepaid expenses and other assets on the consolidated balance sheet. The NMBCT Trusts are considered variable interest entities. Since the Parent Company is not the primary beneficiary of the NMBCT Trusts, the financial statements of the NMBCT Trusts are not included in our consolidated financial statements.

NOTE 9 -Earnings Per Share

Basic earnings per share, excluding dilution, is computed by dividing earnings available to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock or resulted in the issuance of common stock that could then share in our earnings.

The following table sets forth the computation of basic and diluted earnings per share of common stock:

Long-term incentive plan grants for 43,604 shares of common stock were not considered in computing diluted earnings per share for the three months ended March 31, 2026, because they were antidilutive. There wereno antidilutive shares for the three months ended March 31, 2025.

NOTE 10 -Stockholders’ Equity

Preferred stock

As of March 31, 2026 and December 31, 2025, the Company had 10,000,000 shares of preferred stock authorized, $0.0001 par value, of which none were issued or outstanding, respectively.

Common stock

Voting

As of March 31, 2026 and December 31, 2025, the Company had 80,000,000 and 50,000,000 shares of voting common stock authorized, respectively, $0.0001 par value, of which 27,935,888 and 27,887,337 shares were issued and outstanding, respectively.

Non-Voting

As of March 31, 2026 the Company had 20,000,000 shares of non-voting common stock authorized, $0.0001 par value, of which none were issued and outstanding. As of December 31, 2025 the Company wasnot authorized to issue shares of non-voting common stock.

Dividends:

Dividends paid by the Company, if any, are substantially provided from Bank dividends. The Bank may declare dividends without prior regulatory approval that do not exceed the total of retained net income for the current year combined with its retained net income for the precedingtwo years, subject to maintenance of minimum capital requirements. Dividends received from subsidiaries were as follows for the three months ended March 31,:

The Parent Company did not declare or pay any dividend to stockholders for the three months ended March 31, 2026 and 2025.

Equity Incentive Plans:

2017 Equity Incentive Plan

The 2017 Equity Incentive Plan (the “2017 Plan”) provides for the grant of stock options, stock appreciation rights, restricted stock and other stock awards to its employees, directors and consultants for up to 1,977,292 shares of FirstSun common stock in the aggregate.

Option awards are generally granted with an exercise price of not less than the fair value of a share of the Company’s common stock at the date of grant, they vest 25% on the first, second, third and fourth anniversaries following the date of grant and have 10 year terms. The fair value of each stock option award is estimated on the date of grant utilizing the Black-Scholes option pricing model. Expected volatility was determined based on the median historical volatility of 25 to 30 comparable companies that were publicly traded for a period commensurate with the expected term of the options. The expected term of the options was estimated to be the average of the vesting term and time to expiration. The risk-free rate for the expected term of the stock options was based on the U.S. Treasury yield curve in effect at the date of grant.

The following table presents stock options outstanding as of and for the three months ended March 31,:

At March 31, 2026, there wasno unrecognized compensation cost related to non-vested stock options. At March 31, 2026 and 2025, the intrinsic value of the stock options was $10,653 and $14,089, respectively.

2021 Equity Incentive Plan

The FirstSun Capital Bancorp 2021 Equity Incentive Plan (the “2021 Plan”) provides for the grant of stock options, stock appreciation rights, restricted stock and other stock awards to its employees, directors and consultants for up to 2,476,571 shares of FirstSun common stock in the aggregate. Additionally, we established the FirstSun Capital Bancorp Long-Term Incentive Plan (“LTIP”), which became effective April 1, 2022. The LTIP is intended to qualify as a “top-hat” plan under ERISA that is unfunded and provides benefits only to a select group of management or highly compensated employees of FirstSun or the Bank.

Restricted stock and restricted stock units:

The following table presents non-vested restricted stock units outstanding with only a service condition as of and for the three months ended March 31,:

At March 31, 2026, there was $3,845 of total unrecognized compensation cost related to the non-vested restricted stock.

Performance share units:

We determine the shares to be issued based on actual and forecast results during the requisite performance period to determine the probability the market or performance conditions will be achieved. Performance share units outstanding at March 31, 2026 are as follows:

The following table presents performance share unit activity at target for the three months ended March 31,:

Acquired Equity Incentive Plans

In conjunction with the Pioneer merger, we assumed certain options that had been granted under Pioneer’s option plans. All assumed options were fully vested and exercisable. No further options will be granted under the Pioneer plans. The following table presents option activity for the three months ended March 31,:

At March 31, 2026 and 2025, the intrinsic value of the stock options was $120 and $1,167, respectively.

For the three months ended March 31, 2026 and 2025, we recorded total compensation cost from the Equity Incentive Plans of $1,255 and $636, respectively.

NOTE 11 -Income Taxes

The provision for income taxes in interim periods requires us to make an estimate of the effective tax rate expected to be applicable for the full year, adjusted for any discrete items for the applicable period. This estimated effective tax rate is then applied to interim consolidated pre-tax operating income to determine the interim provision for income taxes.

The provision for income tax is summarized as follows:

We do not believe that we have any material uncertain tax positions, and do not expect any material changes during the next twelve months.

NOTE 12 -Regulatory Capital Matters

Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action.

Under the Basel III rules, the Parent Company and the Bank must hold a capital conservation buffer above the adequately capitalized risk-based capital ratios. The fully phased in capital conservation buffer is 2.50% for all periods presented.

The net unrealized gain or loss on available for sale securities is not included in computing regulatory capital. As of March 31, 2026, both the Parent Company and the Bank met all capital adequacy requirements to which they were subject.

Prompt corrective action regulations provide five classifications: well-capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If adequately capitalized, regulatory approval is required to accept brokered deposits. If undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. As of March 31, 2026 and December 31, 2025, the most recent regulatory notifications categorized the Bank as well-capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category.

Actual and required capital amounts for the Parent Company are as follows as of:

Actual and required capital amounts for the Bank are as follows as of:

NOTE 13 -Fair Value Measurements

We utilize fair value measurements to record or disclose the fair value on certain assets and liabilities. Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The determination of fair values of financial instruments often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation models rely on market-based parameters when available, such as interest rate yield curves or credit spreads. Unobservable inputs may be based on management’s judgment assumptions and estimates related to credit quality, our future earnings, interest rates and other relevant inputs. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and the methods used.

ASC Topic 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. The hierarchy is based on the transparency of the inputs used in the valuation process with the highest priority given to quoted prices available in active markets and the lowest priority to unobservable inputs where no active market exists. The three levels of inputs that may be used to measure fair value are as follows:

Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

Level 3: Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own beliefs about the assumptions that market participants would use in pricing the assets or liabilities.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input within the valuation hierarchy that is significant to the overall fair value measurement. Transfers between levels of the fair value hierarchy are recognized at the end of the reporting period.

The following table sets forth our assets and liabilities measured at fair value on a recurring basis as of:

For further details on our Level 3 inputs related to MSRs, see Note 5 - Mortgage Servicing Rights.

The following table presents a reconciliation for our Level 3 assets measured at fair value on a recurring basis:

Certain financial assets and financial liabilities are regularly measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. Financial assets measured at fair value on a non-recurring basis during the reported periods include certain collateral dependent loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral and other real estate owned and foreclosed assets, which, upon initial recognition, were remeasured and reported at fair value through a charge-off to the allowance for credit losses, and subsequent to their initial recognition, were remeasured at fair value through a write-down included in other noninterest expense. The following table sets forth our assets and liabilities that were measured at fair value on a non-recurring basis as of:

The fair value of the financial assets in the table above utilizes the market approach valuation technique, with discount adjustments for differences between comparable sales.

Fair value of financial instruments not carried at fair value:

The carrying amounts and estimated fair values of financial instruments not carried at fair value are as follows as of:

NOTE 14 -Segment Information

The Company’s Chief Executive Officer has been identified as the chief operating decision maker (“CODM”), who oversees the operations conducted through ourtwo primary operating segments: Banking and Mortgage Operations. Corporate represents costs not allocated to the operating segments, including those of FirstSun and our non-bank subsidiaries.

The Banking segment originates loans and provides deposits and fee-based services to consumer, business, and mortgage lending customers. Products offered include a full range of commercial and consumer banking and financial services. The interest income on loans held-for-investment is recognized in the Banking segment, excluding newly originated residential first mortgages within the Mortgage Operations segment.

The Mortgage Operations segment originates, sells, services, and manages market risk from changes in interest rates on one-to-four family residential mortgage loans to sell or hold on our balance sheet. Loans originated-to-sell comprise the majority of the lending activity. The Mortgage Operations segment recognizes interest income on loans that are held-for-sale and newly originated residential mortgages held-for-investment, the gains from one to four family residential mortgage sales, and revenue for servicing loans and other ancillary fees following a sales transaction. Revenue from servicing activities is earned on a contractual fee basis. The Mortgage Operations segment services loans for the held-for-investment portfolio, for which it earns revenue via an intercompany service fee allocation which appears as a cost to Banking in mortgage fees. Forward traded loan purchases and sales settlements as well as mortgage servicing rights and related fair value adjustments are reported in this segment.

Corporate represents miscellaneous other expenses of a corporate nature as well as revenue and expenses not directly assigned or allocated to the Banking or Mortgage Operations segments. The majority of executive management’s time is spent managing operating segments; related costs have been allocated between the operating segments and Corporate.

Allocations of expenses to the operating segments are based on estimated uses of those services. We use a funds transfer pricing process to allocate costs, capital and resources to each operating segment. This allows us to identify the cost of funds within each segment, measure the profitability of each segment by relating costs to revenue, and to evaluate each operating segment’s impact on consolidated earnings. Our CODM reviews net income to budgeted net income to assess segment performance on a monthly basis and to make decisions about allocating capital and personnel to the segments.

Significant segment totals are reconciled to the financial statements as follows for the three months ended March 31,:

NOTE 15 -Commitments and Contingencies

Commitments

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include loan commitments, standby letters of credit, and documentary letters of credit and involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements. Our exposure to credit loss in the event of nonperformance by the other party of these loan commitments and standby letters of credit is represented by the contractual amount of those instruments. We use the same credit policies in making commitments and conditional obligations as we do for on-balance sheet financial instruments.

Undistributed portion of committed loans and unused lines of credit

Loan commitments are agreements to lend to a customer as long as there is no customer violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require a payment of a fee. As of March 31, 2026 and December 31, 2025, commitments included the funding of fixed-rate loans totaling $130,411 and $130,867 and variable-rate loans totaling $1,413,607 and $1,372,506, respectively. The fixed-rate loan commitments have interest rates ranging from 1.00% to 18.00% at March 31, 2026 and December 31, 2025, and maturities ranging from 7 months to 17 years at March 31, 2026 and 1 month to 17 years at December 31, 2025.

Standby letters of credit

Standby letters of credit are conditional commitments to guarantee the performance of a customer to a third-party. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Since many loan commitments and letters of credit expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on our credit evaluation of the counterparty. Collateral held varies but may include accounts receivable, inventory, property, plant and equipment, owner occupied real estate, and/or income-producing commercial properties. As of March 31, 2026 and December 31, 2025, our standby letters of credit commitment totaled $37,005 and $39,356, respectively.

MPF Master Commitments

The Bank has executed MPF Master Commitments (Commitments) with the FHLB to deliver mortgage loans and to guarantee the payment of any realized losses that exceed the FHLB’s first loss account for mortgages delivered under the Commitments. The Bank receives credit enhancement fees from the FHLB for providing this guarantee and continuing to manage the credit risk of the MPF Program mortgage loans. As of March 31, 2026 and December 31, 2025, the Bank considered the amount of any of its liability for the present value of the credit enhancement fees less any expected losses in the mortgages delivered under the Commitments to be immaterial, and has not recorded a liability and offsetting receivable. As of March 31, 2026 and December 31, 2025, the maximum potential amount of future payments that the Bank would have been required to make under the Commitments was $5,888 and $4,600, respectively. Under the Commitments, the Bank agrees to service the loans and therefore, is responsible for any necessary foreclosure proceedings. Any future recoveries on any losses would not be paid by the FHLB under the Commitments. The Bank has not experienced any material losses under these guarantees.

Contingencies

We generally sell loans to investors without recourse; therefore, the investors have assumed the risk of loss or default by the borrower. However, we are usually required by these investors to make certain standard representations and warranties relating to credit information, loan documentation, and collateral. To the extent that we do not comply with such representations, we may be required to repurchase the loans or indemnify these investors for any losses from borrower defaults. We establish reserves for potential losses related to these representations and warranties if deemed appropriate and such reserves would be recorded within accrued expenses and other liabilities. In assessing the adequacy of the reserve, we evaluate various factors including actual write-offs during the period, historical loss experience, known delinquent and other problem loans, and economic trends and conditions in the industry.

Litigation

From time to time, we are a defendant in various claims, legal actions, and complaints arising in the ordinary course of business. We periodically review all outstanding pending or threatened legal proceedings and determine if such matters will have an adverse effect on our business, financial condition, results of operations or cash flows.

We establish reserves for contingencies, including legal proceedings, when potential losses become probable and can be reasonably estimated.

NOTE 16 -Lease Commitments

Our leases relate primarily to office space and bank branches with remaining lease terms of generally 1 to 15 years. Certain lease arrangements contain extension options which typically range from 5 to 10 years at the then fair market rental rates. As these extension options are not generally considered reasonably certain of exercise, they are not included in the lease term.

The following table reconciles future undiscounted lease payments due under non-cancelable operating leases to the aggregate operating lessee lease liability as of March 31, 2026:

Total lease expense for three months ended March 31, 2026 and 2025 was $2,268 and $2,036, respectively. The components of total lease expense were as follows:

We do not currently have any significant finance leases in which we are the lessee, material related-party leases, leases containing residual value guarantees or restrictive covenants.

NOTE 17 -Subsequent Events

The Company has evaluated subsequent events for potential recognition and disclosure through the filing date of this Form 10-Q.

See Note 2 - Acquisition of First Foundation Inc. for details on the completion of our previously announced merger with First Foundation on April 1, 2026.
