Accounting Policies [Abstract]
Organization and Basis of Presentation	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” or “Sunflower Bank”), Logia Portfolio Management, LLC, and FEIF Capital Partners, LLC, and have been prepared using U.S. generally accepted accounting principles (“U.S. 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”. These consolidated financial statements in this Quarterly Report on Form 10-Q do not include all of the information and footnotes required by U.S. 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. Certain prior period amounts have been reclassified to conform to the current presentation. 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, 2023, included in our 2023 Annual Report . Proposed Merger with HomeStreet - On April 30, 2024, FirstSun entered into Amendment No. 1 (the “Amendment”) to the Agreement and Plan of Merger, dated January 16, 2024 (the “Merger Agreement”), by and among HomeStreet, Inc., a Washington corporation (“HomeStreet”), FirstSun, and Dynamis Subsidiary, Inc., a Washington corporation and wholly owned subsidiary of FirstSun (“Merger Sub”). On the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into HomeStreet, with HomeStreet continuing as the surviving entity (the “Merger”), and immediately following the Merger, HomeStreet will merge with and into FirstSun (the “Second-Step Merger”), with FirstSun continuing as the surviving corporation (the “Surviving Entity”). Promptly following the Second-Step Merger, HomeStreet Bank, a Washington-chartered non-member bank (“HomeStreet Bank”), and, as of immediately prior to the Second-Step Merger, a wholly owned subsidiary of HomeStreet, will merge with and into Sunflower Bank (the “Bank Merger” and together with the Merger and the Second-Step Merger, the “Mergers”), with Sunflower Bank continuing as the surviving bank. The Amendment changed the structure of the Bank Merger, so that Sunflower Bank will convert from a national banking association into a Texas state-chartered bank that is a member of the Federal Reserve System (“New Parent Bank”), and HomeStreet Bank will merge with and into New Parent Bank, with New Parent Bank as the surviving entity in the Bank Merger. Following the Bank Merger, the New Parent Bank will continue to operate the assumed branches of HomeStreet Bank under the “HomeStreet Bank” name and brand. Under the terms of the Merger Agreement, as amended by the Amendment, shareholders of HomeStreet will receive, in respect of each share of common stock of HomeStreet held by them, 0.3867 shares of common stock of FirstSun. Shareholders of HomeStreet, subject to other exceptions, will also be entitled to receive cash in lieu of fractional shares of common stock of FirstSun. The combined entity’s expanded footprint includes, FirstSun’s current presence in the Southwest and Midwest together with HomeStreet’s presence in Southern California, Hawaii and the Pacific Northwest. Investment Agreements Upfront Securities Purchase Agreement - Concurrently with entry into the Merger Agreement, FirstSun entered into an upfront securities purchase agreement (the “Upfront Securities Purchase Agreement”) with certain funds managed by Wellington Management Company, LLP (collectively, the “Wellington Funds”), pursuant to which we issued 2.46 million shares of our common stock in a private placement for $80.0 million. Under the terms of the Upfront Securities Purchase Agreement, FirstSun is also obligated, concurrently with the closing of the proposed HomeStreet merger, to issue to the Wellington Funds, warrants (the “Warrants”) to purchase approximately 1.15 million shares of FirstSun common stock with such Warrants having an initial exercise price of $32.50 per share. The Warrants will carry a term of three years. In the event the proposed HomeStreet merger is not consummated, no Warrants will be issued. Acquisition Finance Securities Purchase Agreement - Concurrently with its entry into the HomeStreet merger agreement, FirstSun entered into an acquisition finance securities purchase agreement (the “Acquisition Finance Securities Purchase Agreement,” and together with the Upfront Securities Purchase Agreement, as the “Investment Agreements”), dated January 16, 2024, with the Wellington Funds. Pursuant to the Acquisition Finance Securities Purchase Agreement, on the terms and subject to the conditions set forth therein, substantially concurrently with the closing of the merger, the institutional investors will invest an aggregate of $95 million in exchange for the sale and issuance, at a purchase price of $32.50 per share, of approximately 2.92 million shares of FirstSun common stock. Concurrently with its entry into the Amendment, on April 30, 2024, FirstSun entered into a First Amendment to the Acquisition Finance Securities Purchase Agreement (the “AFSPA Amendment”), with certain funds managed by Wellington Management (“Wellington”) and certain other institutional accredited investors (each, an “Additional Investor” and, collectively with Wellington, the “Investors”). Pursuant to the AFSPA Amendment, on the terms and subject to the conditions set forth therein, substantially concurrently with the closing of the Merger, the Additional Investors will invest an additional $45 million, in exchange for the sale and issuance, at a purchase price of $32.50 per share, approximately 1.38 million shares of FirstSun common stock. Under the terms of the AFSPA Amendment, FirstSun has the ability to offer an additional approximately 462 thousand shares, at a purchase price of $32.50 per share, for an additional investment of $15 million and Castle Creek Capital Partners VIII. L.P., one of the Additional Investors, has a 30 day window to purchase those shares. Registration Rights Agreements - In connection with the Upfront Securities Purchase Agreement, FirstSun and the Wellington Funds also entered into a registration rights agreement (the “Upfront Registration Rights Agreement”), dated January 16, 2024, pursuant to which FirstSun agreed to, among other things, provide customary resale registration rights with respect to the shares of our common stock obtained by the Wellington Funds pursuant to the Investment Agreements, including those issued upon exercise of the Warrants. In addition, the Acquisition Finance Securities Purchase Agreement contemplates that, in connection with the closing of the investments under the Acquisition Finance Securities Purchase Agreement, FirstSun will enter into a resale registration rights agreement with each additional institutional investor (the “Acquisition Finance Registration Rights Agreement”), the material terms and conditions of which are consistent with the terms and conditions of the Upfront Registration Rights Agreement. Charter Amendment - In connection with the proposed merger, the holders of a majority of the voting power of FirstSun common stock e xecuted a written consent approving and adopting an amendment to our certificate of incorporation (the “Charter Amendment”) which will increase the number of FirstSun’s authorized shares of capital stock from 60,000,000 to 110,000,000, consisting of 100,000,000 shares of FirstSun common stock, and 10,000,000 shares of preferred stock and will become effective upon FirstSun’s filing the Charter Amendment with the Secretary of State of the State of Delaware. We plan to file the Charter Amendment prior to the closing of the proposed merger. Bank Charter Conversion - Sunflower Bank is currently regulated by the Office of the Comptroller of the Currency. We have announced our intention to convert Sunflower Bank to a state chartered bank regulated by the Texas Department of Banking and to seek membership with the Federal Reserve later this year. Use of Estimates - The preparation of consolidated financial statements in conformity with U.S. 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. Risks and Uncertainties - In the normal course of business, companies in the banking and mortgage industries encounter certain economic and regulatory risks. Economic risks include credit risk, interest rate risk, liquidity risk, prepayment risk, and market risk. Credit risk is the risk of default that may result from the borrowers’ inability or unwillingness to make contractually required payments. We are subject to interest rate risk to the extent that in a rising interest rate environment we may experience a decrease in loan production, as well as decreases in the value of mortgage loans held-for-sale and in commitments to originate loans, which may adversely impact our earnings. Rising interest rates may also increase the cost of our borrowings to fund our operations. Risks related to liquidity are heightened in the current environment due to competition for deposits and customers withdrawing deposits in order to maintain maximum levels of deposit insurance. 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, or there are early payment defaults, we may be required to repurchase the loans or indemnify these investors for any losses from borrower defaults. In addition, if loans pay off within a specified time frame, we may be required to refund a portion of the sales proceeds to the investors. We established reserves for potential losses related to these representations and warranties which are recorded within accrued expenses and other liabilities. In assessing the adequacy of the reserves, 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. Further information is presented in Note 16 - Commitments and Contingencies . Reclassifications - Some items in the prior year financial statements were reclassified to conform to the current presentation. 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. In June of 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments , which significantly changes the way that entities are required to measure credit losses. The new standard requires that the estimated credit loss be based upon an “expected credit loss” approach rather than the “incurred loss” approach previously required. The new approach requires entities to measure all expected credit losses for financial assets over their expected lives based on historical experience, current conditions, and reasonable and supportable forecasts of collectability. The expected credit loss model requires earlier recognition of credit losses than the incurred loss approach. We expect ongoing changes in the allowance for credit losses will be driven primarily by the growth of our loan portfolio, credit quality, and the economic environment and related projections at that time. In addition, the ASU developed a new accounting treatment for purchased financial assets with credit deterioration. The ASU also modifies the other-than-temporary impairment model for available-for-sale debt securities and held-to-maturity debt securities by requiring companies to record an allowance for credit impairment rather than write-downs of such assets. Management has reviewed this update and other ASUs that were subsequently issued to further clarify the implementation guidance outlined in ASU 2016-13. We adopted the amendments of these ASUs as of January 1, 2023. Upon adoption, we recorded an increase to the allowance for credit losses on loans held-for-investment of $5.3 million, a reduction in the allowance for credit losses on unfunded commitments of $0.2 million, an increase to deferred tax assets of $1.2 million, and a corresponding one-time cumulative reduction to retained earnings, net of tax, of $3.8 million in the consolidated balance sheet as of January 1, 2023. The adoption of this ASU, as it relates to available-for-sale debt securities and held-to-maturity debt securities, did not have a material impact on the consolidated financial statements as of January 1, 2023. Recent Accounting Pronouncements Not Yet Adopted - ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” ASU 2023-07 expands segment disclosure requirements for public entities to require disclosure of significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. ASU 2023-07 is not expected to have a significant impact on our financial statements. ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” ASU 2023-09 requires public business entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if items meet a quantitative threshold. ASU 2023-09 also requires all entities to disclose income taxes paid, net of refunds, disaggregated by federal, state and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold, among other things. ASU 2023-09 is effective for us on January 1, 2026, although early adoption is permitted. ASU 2023-09 is not expected to have a significant impact on our financial statements.

We do not have plans to sell any of the available-for-sale debt securities with unrealized losses as of March 31, 2024, 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, 2024, 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, 2024 are summarized in the following table.

As of March 31, 2024 and December 31, 2023, we had an allowance for credit losses on unfunded commitments of $1,949 and $2,309, respectively. For the three months ended March 31, 2024 and 2023 we recorded a (benefit) provision for credit losses on unfunded commitments of $(360) and $20, respectively. The provision for credit losses, including the benefit for unfunded commitments, totaled $16.5 million during the three months ended March 31, 2024. The provision was primarily due to a $17.4 million charge-off on a specific customer in our C&I loan portfolio.

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”.

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, 2024. 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 table presents loan modifications for borrowers experiencing financial difficulty during the 12 months ended March 31, 2024, segregated by modification type, regardless of whether such modifications resulted in a new loan. Payment Interest Rate Reduction % of Commercial and industrial $ 283 $ — — % Commercial real estate: Owner occupied — 1,777 0.3 % Total loans $ 283 $ 1,777 0.3 % There were no commitments to lend additional funds to these borrowers at March 31, 2024. The financial effects of our loan modifications made to borrowers experiencing financial difficulty during the 12 months ended March 31, 2024 were not significant. We closely monitor the performance of loan modifications made to borrowers experiencing financial difficulty to understand the effectiveness of the modification efforts.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	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: Number of Expiration Outstanding Estimated March 31, 2024 Derivative financial instruments designated as hedging instruments: Assets: Interest Rate Products 31 2025 - 2036 $ 180,633 $ 15,607 Derivative financial instruments not designated as hedging instruments: Assets: Interest Rate Products 49 2024 - 2037 $ 394,076 $ 23,397 Other 1 2025 $ 7,759 $ 1 Liabilities: Interest Rate Products 49 2024 - 2037 $ 394,076 $ 23,188 Other 2 2028 $ 6,168 $ 18 December 31, 2023 Derivative financial instruments designated as hedging instruments: Assets: Interest Rate Products 32 2028 - 2036 $ 195,935 $ 12,737 Derivative financial instruments not designated as hedging instruments: Assets: Interest Rate Products 49 2024 - 2037 $ 396,111 $ 19,931 Other 1 2025 $ 14,638 $ 7 Liabilities: Interest Rate Products 49 2024 - 2037 $ 396,111 $ 19,869 Other 2 2028 $ 6,168 $ 30 We recorded gains and losses on banking derivative assets and liabilities as follows: For the three months ended March 31, 2024 2023 Recorded gain (loss) on banking derivative assets $ 6,385 $ (2,560) Recorded (loss) gain on banking derivative liabilities $ (6,232) $ 2,256 For the three months ended March 31, 2024 and 2023, our banking derivative financial instruments not designated as hedging instruments generated fee income of $31 and $466, respectively. The carrying amount of hedged loans receivable as of March 31, 2024 and December 31, 2023 was $167,817 and $184,829, respectively. The cumulative amount of fair value hedging adjustment included in the carrying amount of the hedged loans receivable as of March 31, 2024 and December 31, 2023 was $(11,161) and $(9,567), respectively. The carrying amount of hedged securities available-for-sale as of March 31, 2024 and December 31, 2023 was $37,213 and $37,701, respectively. The cumulative amount of fair value hedging adjustment, net of tax included in other comprehensive income as of March 31, 2024 and December 31, 2023 was $3,353, and $218, 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.

We incurred and capitalized $534 of costs related to the issuance of the subordinated note. The amortization associated with the capitalized issuance costs is not 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 (three-month LIBOR as of March 31, 2023) plus 3.35% (8.91% and 8.08% as of March 31, 2024 and 2023, respectively) for the trust preferred securities issued through NMBCT I and at a rate of three-month term SOFR (three-month LIBOR as of March 31, 2023) plus 2.00% (7.58% and 6.92% as of March 31, 2024 and 2023, respectively) for the trust preferred securities issued through NMBCT II.

Earnings Per Share [Abstract]
Earnings Per Share	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: For the three months ended March 31, 2024 2023 Net income applicable to common stockholders $ 12,296 $ 26,281 Weighted Average Shares Weighted average common shares outstanding 27,019,625 24,923,259 Effect of dilutive securities Stock-based awards 609,316 564,323 Weighted average diluted common shares 27,628,941 25,487,582 Earnings per common share Basic earnings per common share $ 0.46 $ 1.05 Effect of dilutive securities Stock-based awards (0.01) (0.02) Diluted earnings per common share $ 0.45 $ 1.03 Convertible notes payable for 85,500 shares of common stock were not considered in computing diluted earnings per share for the three months ended March 31, 2023, because they were antidilutive.

As of March 31, 2024 and December 31, 2023, the Company has 50,000,000 shares of common stock authorized, $0.0001 par value, of which 27,442,943 and 24,960,639 shares were issued and outstanding, respectively. For potential changes to our authorized shares as a result of our proposed merger with HomeStreet, see Charter Amendment in Note 1 - Organization and Basis of Presentation . Upfront Securities Purchase Agreement On January 16, 2024 in accordance with the Upfront Securities Purchase Agreement, we issued we 2,461,538 shares of our common stock in a private placement for $80.0 million. For additional details see Upfront Securities Purchase Agreement in Note 1 - Organization and Basis of Presentation . 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. The following table presents stock options outstanding as of and for the three months ended March 31, 2024. Shares Weighted-Average Exercise Price, per Share Weighted-Average Remaining Contractual Term (years) Outstanding, beginning of period 1,245,000 $ 20.25 Exercised (26,943) 19.72 Outstanding, end of period 1,218,057 $ 20.27 4.06 Options vested or expected to vest 1,218,057 $ 20.27 Options exercisable, end of period 1,211,582 $ 20.20 4.04 There were no grants or forfeitures during the three months ended March 31, 2024: At March 31, 2024, there was $89 of total unrecognized compensation cost related to non-vested stock options. The unrecognized compensation cost at March 31, 2024 is expected to be recognized over the following two years. At March 31, 2024 the intrinsic value of the stock options was $18,154. 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. In March 2024, we granted special restricted stock awards of 424,098 shares to certain officers of the Company for (i) retention purposes and (ii) to incentivize them in their efforts to work towards both a timely and efficient consummation of our merger with HomeStreet and a successful post-closing integration of the two companies. These awards are subject to and conditioned upon closing of the merger with HomeStreet, provided that if the closing of the merger does not occur, the awards will be cancelled. Because the special restricted stock awards are contingent upon the closing of the merger with HomeStreet, no expense has been incurred during the three months ended March 31, 2024 . These awards will vest one-third per year over a three-year period, provided that the officer continues to provide services to the Company on the applicable vesting date, with accelerated vesting upon death, disability, or termination by the Company under certain conditions. In March 2024, we issued 11,739 shares of restricted stock that will fully vest in March 2025. In May 2023, we issued 15,007 shares of restricted stock that will fully vest in May 2024. In May 2022, we issued 11,344 shares of restricted stock that were fully vested in May 2023. At March 31, 2024, there was $555 of total unrecognized compensation cost related to the non-vested restricted stock. In May 2023, we issued performance-based restricted stock under the LTIP that, subject to the achievement of performance conditions, will fully vest in April 2026. At March 31, 2024, we determined it is probable that 64,455 shares will be issued based upon the probability that the performance conditions will be achieved. At March 31, 2024, there was $1,222 of total unrecognized compensation cost related to the non-vested restricted stock granted on these probable shares. In May 2022, we issued performance-based restricted stock under the LTIP that, subject to the achievement of performance conditions, will fully vest in April 2025. At March 31, 2024, we determined it is probable that 52,795 shares will be issued based upon the probability that the performance conditions will be achieved. At March 31, 2024, there was $628 of total unrecognized compensation cost related to the non-vested restricted stock granted on these probable shares. For the three months ended March 31, 2024 and 2023, we recorded total compensation cost from the 2017 and 2021 Plans of $492 and $426, respectively. Acquired Equity Incentive Plans In conjunction with a previous acquisition, we assumed certain options that had been granted under such option plans. All assumed options were fully vested and exercisable. No further options will be granted under the plans.

Regulatory Capital Requirements under Banking Regulations [Abstract]
Regulatory Capital Matters	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, 2024, 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, 2024 and December 31, 2023, 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 For Capital To be Well- Amount Ratio Amount Ratio Amount Ratio March 31, 2024 Total risk-based capital to risk-weighted assets: $ 1,045,877 14.73 % $ 567,975 8.00 % N/A N/A Tier 1 risk-based capital to risk-weighted assets: $ 890,558 12.54 % $ 425,982 6.00 % N/A N/A Common Equity Tier 1 (CET 1) to risk-weighted assets: $ 890,558 12.54 % $ 319,486 4.50 % N/A N/A Tier 1 leverage capital to average assets: $ 890,558 11.73 % $ 303,585 4.00 % N/A N/A December 31, 2023 Total risk-based capital to risk-weighted assets: $ 953,331 13.25 % $ 575,434 8.00 % N/A N/A Tier 1 risk-based capital to risk-weighted assets: $ 798,167 11.10 % $ 431,575 6.00 % N/A N/A Common Equity Tier 1 (CET 1) to risk-weighted assets: $ 798,167 11.10 % $ 323,682 4.50 % N/A N/A Tier 1 leverage capital to average assets: $ 798,167 10.52 % $ 303,410 4.00 % N/A N/A Actual and required capital amounts for the Bank are as follows as of: Actual For Capital To be Well- Amount Ratio Amount Ratio Amount Ratio March 31, 2024 Total risk-based capital to risk-weighted assets: $ 933,996 13.18 % $ 566,996 8.00 % $ 708,745 10.00 % Tier 1 risk-based capital to risk-weighted assets: $ 854,122 12.05 % $ 425,247 6.00 % $ 566,996 8.00 % Common Equity Tier 1 (CET 1) to risk-weighted assets: $ 854,122 12.05 % $ 318,935 4.50 % $ 460,684 6.50 % Tier 1 leverage capital to average assets: $ 854,122 11.27 % $ 303,044 4.00 % $ 378,805 5.00 % December 31, 2023 Total risk-based capital to risk-weighted assets: $ 918,050 12.79 % $ 574,280 8.00 % $ 717,850 10.00 % Tier 1 risk-based capital to risk-weighted assets: $ 838,199 11.68 % $ 430,710 6.00 % $ 574,280 8.00 % Common Equity Tier 1 (CET 1) to risk-weighted assets: $ 838,199 11.68 % $ 323,033 4.50 % $ 466,603 6.50 % Tier 1 leverage capital to average assets: $ 838,199 11.05 % $ 303,321 4.00 % $ 379,151 5.00 %

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	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 judgement assumptions and estimates related to credit quality, our future earnings, interest rates and other relevant inputs. These valuation methods require considerable judgement 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: Level 1 Level 2 Level 3 Quoted prices Significant Significant Total March 31, 2024 Available-for-sale securities $ 48,078 $ 451,000 $ — $ 499,078 Loans held-for-sale — 56,813 — 56,813 Mortgage servicing rights — — 78,416 78,416 Derivative financial instruments - assets — 40,279 — 40,279 Derivative financial instruments - liabilities — (23,206) — (23,206) Total $ 48,078 $ 524,886 $ 78,416 $ 651,380 December 31, 2023 Available-for-sale securities $ 54,234 $ 462,523 $ — $ 516,757 Loans held-for-sale — 54,212 — 54,212 Mortgage servicing rights — — 76,701 76,701 Derivative financial instruments - assets — 35,073 — 35,073 Derivative financial instruments - liabilities — (20,475) — (20,475) Total $ 54,234 $ 531,333 $ 76,701 $ 662,268 For further details on our Level 3 inputs related to MSRs, see Note 4 - Mortgage Servicing Rights .

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 non-interest expense.

Segment Information

Segment Information	3 Months Ended
	Mar. 31, 2024
Segment Reporting [Abstract]
Segment Information	Segment Information Our operations are conducted through two operating segments: Banking and Mortgage Operations. Corporate represents costs not allocated to the operating segments. Operating segments are defined as components of an enterprise that engage in business activity from which revenues are earned and expenses are incurred for which discrete financial information is available that is evaluated regularly by executive management in deciding how to allocate resources and in assessing performance. Operating segments have been determined based on the products and services offered and reflect the manner in which financial information is currently evaluated by management. Each segment operates under the same banking charter, but is reported on a segmented basis for this report. Each of the operating segments is complementary to each other and because of the interrelationship of the segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. 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. Revenues are comprised of net interest income before the provision (benefit) for credit losses and noninterest income. Noninterest expenses are allocated to each operating segment. Provision for credit losses is primarily allocated to the Banking segment. Allocation methodologies may be subject to periodic adjustment as management systems evolve and/or the business or product lines within the segments change. Significant segment totals are reconciled to the financial statements as follows for the three months ended March 31,: Banking Mortgage Operations Corporate Total Segments 2024 Summary of Operations Net interest income (loss) $ 68,522 $ 3,519 $ (1,235) $ 70,806 Provision (benefit) for credit losses 17,864 (1,364) — 16,500 Noninterest income: Service charges on deposit accounts 5,768 — — 5,768 Credit and debit card fees 2,802 1 — 2,803 Trust and investment advisory fees 1,463 — — 1,463 Income from mortgage banking services, net (583) 10,085 — 9,502 Other noninterest income 3,272 — — 3,272 Total noninterest income 12,722 10,086 — 22,808 Noninterest expense: Salary and employee benefits 29,763 7,149 441 37,353 Occupancy and equipment 7,759 792 44 8,595 Other noninterest expenses 9,769 3,924 2,187 15,880 Total noninterest expense 47,291 11,865 2,672 61,828 Income (loss) before income taxes $ 16,089 $ 3,104 $ (3,907) $ 15,286 Other Information Depreciation expense $ 1,459 $ 50 $ — $ 1,509 Identifiable assets $ 6,695,912 $ 947,437 $ 138,252 $ 7,781,601 Banking Mortgage Operations Corporate Total Segments 2023 Summary of Operations Net interest income (loss) $ 73,486 $ 1,882 $ (1,251) $ 74,117 Provision for credit losses 2,414 946 — 3,360 Noninterest income: Service charges on deposit accounts 5,015 — — 5,015 Credit and debit card fees 2,981 — — 2,981 Trust and investment advisory fees 1,461 — — 1,461 Income from mortgage banking services, net (188) 7,617 — 7,429 Other noninterest income 2,045 — — 2,045 Total noninterest income 11,314 7,617 — 18,931 Noninterest expense: Salary and employee benefits 27,784 6,772 493 35,049 Occupancy 7,605 710 40 8,355 Other noninterest expenses 8,235 3,509 1,118 12,862 Total noninterest expense 43,624 10,991 1,651 56,266 Income (loss) before income taxes $ 38,762 $ (2,438) $ (2,902) $ 33,422 Other Information Depreciation expense $ 1,649 $ 61 $ — $ 1,710 Identifiable assets $ 6,728,396 $ 819,317 $ 62,743 $ 7,610,456

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	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, 2024 and December 31, 2023, commitments included the funding of fixed-rate loans totaling $204,123 and $191,415 and variable-rate loans totaling $1,485,047 and $1,656,434, respectively. The fixed-rate loan commitments have interest rates ranging from 1.00% to 18.00% at March 31, 2024 and December 31, 2023, and maturities ranging from 1 month to 19 years at March 31, 2024 and from 1 month to 19 years at December 31, 2023. 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 of the 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, 2024 and December 31, 2023, our standby letters of credit commitment totaled $29,448 and $14,490, 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, 2024 and December 31, 2023, 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, 2024 and December 31, 2023, the maximum potential amount of future payments that the Bank would have been required to make under the Commitments was $3,811 and $3,810, 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. 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. Litigation Overdraft Fee Litigation : On September 13, 2021, Samantha Besser filed a putative class action amended complaint against the Bank in the United States District Court for the District of Colorado. The amended complaint alleges that the Bank improperly charged multiple insufficient funds or overdraft fees. The Plaintiff seeks unspecified restitution, actual and statutory damages, costs, attorneys’ fees, pre-judgment interest, and other relief as the Court deems proper . On September 27, 2021, the Bank filed a motion to dismiss the amended complaint, which was denied on March 11, 2024. The case is now in discovery. At this time, the Bank is unable to reasonably estimate the outcome of this litigation. Check Fraud Litigation Rodeo Electrical Services, Inc. and its owner (“RESI”) filed a civil action against the Bank on June 23, 2020 in the Santa Fe County, New Mexico District Court. The complaint alleged that the Bank conspired with or otherwise aided a former RESI employee’s embezzlement of approximately $0.4 million from RESI. The complaint sought compensatory, exemplary, statutory and punitive damages, as well as payment of RESI’s legal fees and expenses. On January 18, 2024, the jury awarded RESI approximately $2.1 million which included punitive damages. Final judgment, which will include post-judgment interest, has not been rendered by the Court. A supplemental award of RESI’s legal fees will likely be entered by July 1, 2024. We believe the judgment will be covered by insurance; therefore, such outcome will not have a material financial impact on the Bank. We establish reserves for contingencies, including legal proceedings, when potential losses become probable and can be reasonably estimated. While the ultimate resolution of any legal proceedings, including the matters described above, cannot be determined at this time, based on information presently available, and after consultation with legal counsel, management believes that the ultimate outcome in these above legal proceedings, either individually or in the aggregate, will not have a material adverse effect on our financial statements. It is possible, however, that future developments could result in an unfavorable outcome for or resolution of any of these proceedings, which may be material to our results of operations for a given fiscal period.

Accounting Policies [Abstract]
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” or “Sunflower Bank”), Logia Portfolio Management, LLC, and FEIF Capital Partners, LLC, and have been prepared using U.S. generally accepted accounting principles (“U.S. 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”. These consolidated financial statements in this Quarterly Report on Form 10-Q do not include all of the information and footnotes required by U.S. 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. Certain prior period amounts have been reclassified to conform to the current presentation. 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, 2023, included in our 2023 Annual Report . Proposed Merger with HomeStreet - On April 30, 2024, FirstSun entered into Amendment No. 1 (the “Amendment”) to the Agreement and Plan of Merger, dated January 16, 2024 (the “Merger Agreement”), by and among HomeStreet, Inc., a Washington corporation (“HomeStreet”), FirstSun, and Dynamis Subsidiary, Inc., a Washington corporation and wholly owned subsidiary of FirstSun (“Merger Sub”). On the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into HomeStreet, with HomeStreet continuing as the surviving entity (the “Merger”), and immediately following the Merger, HomeStreet will merge with and into FirstSun (the “Second-Step Merger”), with FirstSun continuing as the surviving corporation (the “Surviving Entity”). Promptly following the Second-Step Merger, HomeStreet Bank, a Washington-chartered non-member bank (“HomeStreet Bank”), and, as of immediately prior to the Second-Step Merger, a wholly owned subsidiary of HomeStreet, will merge with and into Sunflower Bank (the “Bank Merger” and together with the Merger and the Second-Step Merger, the “Mergers”), with Sunflower Bank continuing as the surviving bank. The Amendment changed the structure of the Bank Merger, so that Sunflower Bank will convert from a national banking association into a Texas state-chartered bank that is a member of the Federal Reserve System (“New Parent Bank”), and HomeStreet Bank will merge with and into New Parent Bank, with New Parent Bank as the surviving entity in the Bank Merger. Following the Bank Merger, the New Parent Bank will continue to operate the assumed branches of HomeStreet Bank under the “HomeStreet Bank” name and brand. Under the terms of the Merger Agreement, as amended by the Amendment, shareholders of HomeStreet will receive, in respect of each share of common stock of HomeStreet held by them, 0.3867 shares of common stock of FirstSun. Shareholders of HomeStreet, subject to other exceptions, will also be entitled to receive cash in lieu of fractional shares of common stock of FirstSun. The combined entity’s expanded footprint includes, FirstSun’s current presence in the Southwest and Midwest together with HomeStreet’s presence in Southern California, Hawaii and the Pacific Northwest. Investment Agreements Upfront Securities Purchase Agreement - Concurrently with entry into the Merger Agreement, FirstSun entered into an upfront securities purchase agreement (the “Upfront Securities Purchase Agreement”) with certain funds managed by Wellington Management Company, LLP (collectively, the “Wellington Funds”), pursuant to which we issued 2.46 million shares of our common stock in a private placement for $80.0 million. Under the terms of the Upfront Securities Purchase Agreement, FirstSun is also obligated, concurrently with the closing of the proposed HomeStreet merger, to issue to the Wellington Funds, warrants (the “Warrants”) to purchase approximately 1.15 million shares of FirstSun common stock with such Warrants having an initial exercise price of $32.50 per share. The Warrants will carry a term of three years. In the event the proposed HomeStreet merger is not consummated, no Warrants will be issued. Acquisition Finance Securities Purchase Agreement - Concurrently with its entry into the HomeStreet merger agreement, FirstSun entered into an acquisition finance securities purchase agreement (the “Acquisition Finance Securities Purchase Agreement,” and together with the Upfront Securities Purchase Agreement, as the “Investment Agreements”), dated January 16, 2024, with the Wellington Funds. Pursuant to the Acquisition Finance Securities Purchase Agreement, on the terms and subject to the conditions set forth therein, substantially concurrently with the closing of the merger, the institutional investors will invest an aggregate of $95 million in exchange for the sale and issuance, at a purchase price of $32.50 per share, of approximately 2.92 million shares of FirstSun common stock. Concurrently with its entry into the Amendment, on April 30, 2024, FirstSun entered into a First Amendment to the Acquisition Finance Securities Purchase Agreement (the “AFSPA Amendment”), with certain funds managed by Wellington Management (“Wellington”) and certain other institutional accredited investors (each, an “Additional Investor” and, collectively with Wellington, the “Investors”). Pursuant to the AFSPA Amendment, on the terms and subject to the conditions set forth therein, substantially concurrently with the closing of the Merger, the Additional Investors will invest an additional $45 million, in exchange for the sale and issuance, at a purchase price of $32.50 per share, approximately 1.38 million shares of FirstSun common stock. Under the terms of the AFSPA Amendment, FirstSun has the ability to offer an additional approximately 462 thousand shares, at a purchase price of $32.50 per share, for an additional investment of $15 million and Castle Creek Capital Partners VIII. L.P., one of the Additional Investors, has a 30 day window to purchase those shares. Registration Rights Agreements - In connection with the Upfront Securities Purchase Agreement, FirstSun and the Wellington Funds also entered into a registration rights agreement (the “Upfront Registration Rights Agreement”), dated January 16, 2024, pursuant to which FirstSun agreed to, among other things, provide customary resale registration rights with respect to the shares of our common stock obtained by the Wellington Funds pursuant to the Investment Agreements, including those issued upon exercise of the Warrants. In addition, the Acquisition Finance Securities Purchase Agreement contemplates that, in connection with the closing of the investments under the Acquisition Finance Securities Purchase Agreement, FirstSun will enter into a resale registration rights agreement with each additional institutional investor (the “Acquisition Finance Registration Rights Agreement”), the material terms and conditions of which are consistent with the terms and conditions of the Upfront Registration Rights Agreement. Charter Amendment - In connection with the proposed merger, the holders of a majority of the voting power of FirstSun common stock e xecuted a written consent approving and adopting an amendment to our certificate of incorporation (the “Charter Amendment”) which will increase the number of FirstSun’s authorized shares of capital stock from 60,000,000 to 110,000,000, consisting of 100,000,000 shares of FirstSun common stock, and 10,000,000 shares of preferred stock and will become effective upon FirstSun’s filing the Charter Amendment with the Secretary of State of the State of Delaware. We plan to file the Charter Amendment prior to the closing of the proposed merger. Bank Charter Conversion
Use of Estimates	The preparation of consolidated financial statements in conformity with U.S. 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.
Risks and Uncertainties	In the normal course of business, companies in the banking and mortgage industries encounter certain economic and regulatory risks. Economic risks include credit risk, interest rate risk, liquidity risk, prepayment risk, and market risk. Credit risk is the risk of default that may result from the borrowers’ inability or unwillingness to make contractually required payments. We are subject to interest rate risk to the extent that in a rising interest rate environment we may experience a decrease in loan production, as well as decreases in the value of mortgage loans held-for-sale and in commitments to originate loans, which may adversely impact our earnings. Rising interest rates may also increase the cost of our borrowings to fund our operations. Risks related to liquidity are heightened in the current environment due to competition for deposits and customers withdrawing deposits in order to maintain maximum levels of deposit insurance.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, or there are early payment defaults, we may be required to repurchase the loans or indemnify these investors for any losses from borrower defaults. In addition, if loans pay off within a specified time frame, we may be required to refund a portion of the sales proceeds to the investors. We established reserves for potential losses related to these representations and warranties which are recorded within accrued expenses and other liabilities. In assessing the adequacy of the reserves, 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.
Reclassifications	Some items in the prior year financial statements were reclassified to conform to the current presentation. 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. In June of 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments , which significantly changes the way that entities are required to measure credit losses. The new standard requires that the estimated credit loss be based upon an “expected credit loss” approach rather than the “incurred loss” approach previously required. The new approach requires entities to measure all expected credit losses for financial assets over their expected lives based on historical experience, current conditions, and reasonable and supportable forecasts of collectability. The expected credit loss model requires earlier recognition of credit losses than the incurred loss approach. We expect ongoing changes in the allowance for credit losses will be driven primarily by the growth of our loan portfolio, credit quality, and the economic environment and related projections at that time. In addition, the ASU developed a new accounting treatment for purchased financial assets with credit deterioration. The ASU also modifies the other-than-temporary impairment model for available-for-sale debt securities and held-to-maturity debt securities by requiring companies to record an allowance for credit impairment rather than write-downs of such assets. Management has reviewed this update and other ASUs that were subsequently issued to further clarify the implementation guidance outlined in ASU 2016-13. We adopted the amendments of these ASUs as of January 1, 2023. Upon adoption, we recorded an increase to the allowance for credit losses on loans held-for-investment of $5.3 million, a reduction in the allowance for credit losses on unfunded commitments of $0.2 million, an increase to deferred tax assets of $1.2 million, and a corresponding one-time cumulative reduction to retained earnings, net of tax, of $3.8 million in the consolidated balance sheet as of January 1, 2023. The adoption of this ASU, as it relates to available-for-sale debt securities and held-to-maturity debt securities, did not have a material impact on the consolidated financial statements as of January 1, 2023. Recent Accounting Pronouncements Not Yet Adopted - ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” ASU 2023-07 expands segment disclosure requirements for public entities to require disclosure of significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. ASU 2023-07 is not expected to have a significant impact on our financial statements. ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” ASU 2023-09 requires public business entities to disclose in their rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in some categories if items meet a quantitative threshold. ASU 2023-09 also requires all entities to disclose income taxes paid, net of refunds, disaggregated by federal, state and foreign taxes for annual periods and to disaggregate the information by jurisdiction based on a quantitative threshold, among other things. ASU 2023-09 is effective for us on January 1, 2026, although early adoption is permitted. ASU 2023-09 is not expected to have a significant impact on our financial statements.
