The results of operations for the six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for any other interim period or the full year ending December 31, 2024. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”). The Company consolidates voting entities in which the Company has control through voting interests or entities through which the Company has a controlling financial interest in a variable interest entity (“VIE”). The Company evaluates its interests in these entities to determine whether they meet the definition of a VIE and whether the Company is required to consolidate these entities. A VIE is consolidated by its primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) a variable interest that could potentially be significant to the VIE. To determine whether or not a variable interest the Company holds could potentially be significant to the VIE, the Company considers both qualitative and quantitative factors regarding the nature, size, and form of the Company's involvement with the VIE. See Note 13 – Variable Interest Entities for additional information.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Standards Adopted in 2024 In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2023-02, Investments - Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, a consensus of the Emerging Issues Task Force . The amendments in this Update allow the option for an entity to apply the proportional amortization method of accounting to other equity investments that are made for the primary purpose of receiving income tax credits or other income tax benefits, if certain conditions are met. Prior to this Update, the application of the proportional amortization method of accounting was limited to investments in low income housing tax credit structures. The proportional amortization method of accounting results in the amortization of applicable investments, as well as the related income tax credits or other income tax benefits received, being presented on a single line in the statements of income, that is income tax expense. Under this Update, an entity has the option to apply the proportional amortization method of accounting to applicable investments on a tax-credit-program-by-tax-credit-program basis. In addition, the amendments in this Update require that all tax equity investments accounted for using the proportional amortization method use the delayed equity contribution guidance in paragraph 323-740-25-3, requiring a liability be recognized for delayed equity contributions that are unconditional and legally binding or for equity contributions that are contingent upon a future event when that contingent event becomes probable. Under this Update, low income housing tax credit investments for which the proportional amortization method is not applied can no longer be accounted for using the delayed equity contribution guidance. Further, this Update specifies that tax equity investments accounted for using the equity method must apply the impairment guidance in Subtopic 323-10 - Investments - Equity Method and Joint Ventures - Overall. This Update also clarifies that for low income housing tax credit investments not accounted for under the proportional amortization method or the equity method, an entity shall account for them under Topic 321 - Investments - Equity Securities. The amendments in this Update also require additional disclosures in interim and annual periods concerning investments for which the proportional amortization method is applied, including (i) the nature of tax equity investments, and (ii) the effect of tax equity investments and related income tax credits and other income tax benefits on the financial position and results of operations. The provisions of this Update became effective for the Company for interim and annual periods beginning January 1, 2024. Refer to Note 14 – Tax Equity Investments for additional information. The adoption of this Update did not have a material impact on the Company’s consolidated financial statements. Recent Accounting Guidance Not Yet Effective In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures . The FASB issued this Update to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this Update address investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid. The amendments in this Update are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this Update on its consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segments . The amendments in this Update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis. Amendments in this Update include: a requirement that a public entity provide all annual disclosures about a reportable segment’s profit or loss in its interim period disclosures, disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), disclosure of amounts for other segment items by reportable segment and a description of its composition, clarification that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit or loss, requires that a public entity disclose the title and position of the CODM, and an explanation of how the CODM uses the reported measure(s) of segment profit or loss, and requires that a public entity that has a single reportable segment provide all the disclosures required by this Update as well as all existing disclosures required in Topic 280. The amendments in this Update are effective for the Company beginning with its 2024 annual financial statement disclosures for the year ended December 31, 2024, and for all interim and annual periods thereafter. Early adoption is permitted. The Company is currently evaluating the impact of this Update.

During the first half of 2024, there were no transfers of AFS securities to HTM securities. During the first half of 2023, the Company transferred $410.7 million of AFS collateralized mortgage obligations to HTM securities. The Company intends and has the ability to hold the securities transferred to maturity. The transfer of these securities was accounted for at fair value on the transfer date. The collateralized mortgage obligations had a net carrying amount of $360.3 million with a pre-tax unrealized loss of $50.4 million, which are accreted into interest income as yield adjustments through earnings over the remaining term of the securities. The amortization of the related net after-tax unrealized losses reported in accumulated other comprehensive loss offsets the effect on interest income for the accretion of the unrealized losses associated with the transferred securities. No gains or losses were recorded at the time of transfer. Investment securities with carrying values of $2.57 billion and $2.80 billion as of June 30, 2024 and December 31, 2023, respectively, were pledged to other borrowings, secure public deposits, and for other purposes as required or permitted by law. Investment securities with carrying values of $2.38 billion and $1.41 billion as of June 30, 2024 and December 31, 2023, respectively, were pledged to the Federal Reserve's discount window to increase the Company’s access to funding and provide liquidity. Unrealized Gains and Losses Unrealized gains and losses on AFS investment securities, net of tax, are recognized in stockholders’ equity as accumulated other comprehensive income or loss. At June 30, 2024, the Company had a net unrealized loss on AFS investment securities of $29.9 million, or $21.4 million net of tax in accumulated other comprehensive loss, compared to a net unrealized loss of $36.0 million, or $25.8 million net of tax in accumulated other comprehensive loss, at December 31, 2023. For investment securities transferred from AFS to HTM, the net after-tax unrealized gains and losses at the date of transfer continue to be reported in stockholders’ equity as accumulated other comprehensive loss and are amortized over the remaining lives of the securities with an offsetting entry to interest income as an adjustment of yield in a manner consistent with the amortization of a premium or discount, with an offsetting entry to interest income for the accretion of the unrealized loss associated with the transferred securities. At June 30, 2024, the unrealized loss on investment securities transferred from AFS to HTM was $95.8 million, or $68.7 million net of tax. At December 31, 2023, the unrealized loss on investment securities transferred from AFS to HTM was $102.9 million, or $73.9 million net of tax. The table below summarizes the number, fair value, and gross unrealized holding losses of the Company’s AFS investment securities in an unrealized loss position for which an allowance for credit losses (the “ACL”) has not been recorded as of the dates indicated, aggregated by investment category and length of time in a continuous loss position.

An ACL on AFS investment securities is recorded when unrealized losses have been deemed, through the Company’s qualitative assessment, to be credit related. Non-credit related unrealized losses on AFS investment securities, which may be attributed to changes in interest rates and other market-related factors, are not recorded through an ACL. Such declines are recorded as an adjustment to accumulated other comprehensive loss, net of tax. In the event the Company is required to sell or has the intent to sell an AFS security that has experienced a decline in fair value below its amortized cost, the Company writes the amortized cost of the security down to fair value in the current period. The ACL for HTM investment securities is estimated on a collective basis, based on shared risk characteristics, and is determined at the individual security level when the Company deems a security to no longer possess shared risk characteristics. Credit losses on HTM investment securities are representative of the amount needed to reduce the amortized cost basis to reflect the net amount expected to be collected. The Company determines credit losses on both AFS and HTM investment securities through the use of a discounted cash flow approach using the security’s effective interest rate. The ACL is measured as the amount by which an investment security’s amortized cost exceeds the net present value of expected future cash flows. However, the amount of credit losses for AFS investment securities is limited to the amount of a security’s unrealized loss. The ACL is established through a charge to provision for credit losses in current period earnings. For additional information concerning the ACL on investment securities, refer to Note 1 - Description of Business and Summary of Significant Accounting Policies , of our audited consolidated financial statements included in our 2023 Form 10-K. At June 30, 2024 and December 31, 2023, the Company had an ACL of $129,000 and $126,000, respectively, for HTM investment securities classified as municipal bonds. The following table presents a rollforward by major security type of the ACL on the Company's HTM debt securities as of and for the periods indicated: Three Months Ended June 30, 2024 (Dollars in thousands) Balance, March 31, 2024 Provision (Recapture) for Credit Losses Balance, June 30, 2024 HTM investment securities: Municipal bonds $ 115 $ 14 $ 129 Three Months Ended June 30, 2023 (Dollars in thousands) Balance, March 31, 2023 Provision (Recapture) for Credit Losses Balance, June 30, 2023 HTM investment securities: Municipal bonds $ 227 $ (114) $ 113 Six Months Ended June 30, 2024 (Dollars in thousands) Balance, December 31, 2023 Provision (Recapture) for Credit Losses Balance, June 30, 2024 HTM investment securities: Municipal bonds $ 126 $ 3 $ 129 Six Months Ended June 30, 2023 (Dollars in thousands) Balance, December 31, 2022 Provision (Recapture) for Credit Losses Balance, June 30, 2023 HTM investment securities: Municipal bonds $ 43 $ 70 $ 113 The Company had no ACL for AFS investment securities at June 30, 2024 and December 31, 2023. The Company performed a qualitative assessment of these investments as of June 30, 2024 and determined that unrealized losses during the second quarter of 2024 were the result of general market conditions, including changes in interest rates, and does not believe the declines in fair value were credit related. As of June 30, 2024, the Company had not recorded credit losses on AFS securities that were in an unrealized loss position due to the high credit quality of the investments, with investment grade ratings, and many of them issued by U.S. government agencies. As of June 30, 2024, 69% of our AFS securities were U.S. Treasury, U.S. government agency, and U.S. government-sponsored enterprise securities. Additionally, the Company continues to receive contractual principal and interest payments in a timely manner. It is more likely than not that the Company will not be required to sell the securities prior to their anticipated recoveries, and at this time the Company does not intend to sell these securities. There was no provision for credit losses recognized for AFS investment securities during the six months ended June 30, 2024 and 2023. At June 30, 2024 and December 31, 2023, there were no AFS or HTM securities on nonaccrual status. All securities in the portfolio were current with their contractual principal and interest payments. At June 30, 2024 and December 31, 2023, there were no securities purchased with deterioration in credit quality since their origination. Realized Gains and Losses The following table presents the amortized cost of securities sold with related gross realized gains, gross realized losses, and net realized gains for the periods indicated: Three Months Ended Six Months Ended June 30, June 30, June 30, June 30, (Dollars in thousands) 2024 2023 2024 2023 Amortized cost of AFS investment securities sold $ — $ — $ — $ 304,182 Gross realized gains $ — $ — $ — $ 986 Gross realized (losses) — — — (848) Net realized gains on sales of AFS investment securities $ — $ — $ — $ 138 Contractual Maturities The amortized cost and estimated fair value of investment securities at June 30, 2024, by contractual maturity, are shown in the table below.

Loans Held for Investment	Loans Held for Investment The Company’s loan portfolio is segmented according to loans that share similar attributes and risk characteristics. Investor loans secured by real estate includes commercial real estate (“CRE”) non-owner-occupied, multifamily, construction, and land, as well as Small Business Administration (“SBA”) loans secured by investor real estate, which are loans collateralized by hotel/motel real property. Business loans secured by real estate are loans to businesses that are collateralized by real estate where the operating cash flow of the business is the primary source of repayment. This loan portfolio includes CRE owner-occupied, franchise loans secured by real estate, and SBA loans secured by real estate, which are collateralized by real property other than hotel/motel real property. Commercial loans are loans to businesses where the operating cash flow of the business is the primary source of repayment. This loan portfolio includes commercial and industrial (“C&I”), franchise loans non-real estate secured, and SBA loans non-real estate secured. Retail loans include single family residential and consumer loans. Single family residential includes home equity lines of credit, as well as second trust deeds. The following table presents the composition of the loan portfolio for the periods indicated: June 30, December 31, (Dollars in thousands) 2024 2023 Investor loans secured by real estate CRE non-owner-occupied $ 2,245,474 $ 2,421,772 Multifamily 5,473,606 5,645,310 Construction and land 453,799 472,544 SBA secured by real estate 33,245 36,400 Total investor loans secured by real estate 8,206,124 8,576,026 Business loans secured by real estate CRE owner-occupied 2,096,485 2,191,334 Franchise real estate secured 274,645 304,514 SBA secured by real estate 46,543 50,741 Total business loans secured by real estate 2,417,673 2,546,589 Commercial loans Commercial and industrial 1,554,735 1,790,608 Franchise non-real estate secured 257,516 319,721 SBA non-real estate secured 10,346 10,926 Total commercial loans 1,822,597 2,121,255 Retail loans Single family residential 70,380 72,752 Consumer 1,378 1,949 Total retail loans 71,758 74,701 Loans held for investment before basis adjustment (1) 12,518,152 13,318,571 Basis adjustment associated with fair value hedge (2) (28,201) (29,551) Loans held for investment 12,489,951 13,289,020 Allowance for credit losses for loans held for investment (183,803) (192,471) Loans held for investment, net $ 12,306,148 $ 13,096,549 Total unfunded loan commitments $ 1,601,870 $ 1,703,470 Loans held for sale, at lower of cost or fair value $ 140 $ — ______________________________ (1) Includes net deferred origination costs (fees) of $1.4 million and $(74,000), and unaccreted fair value net purchase discounts of $38.6 million and $43.3 million as of June 30, 2024 and December 31, 2023, respectively. (2) Represents the basis adjustment associated with the application of hedge accounting on certain loans. Refer to Note 11 – Derivative Instruments for additional information. The Company generally originates SBA loans with the intent to sell the guaranteed portion of the loans prior to maturity and, therefore, designates them as held for sale. From time to time, the Company may purchase or sell other types of loans in order to manage concentrations, maximize interest income, change risk profiles, improve returns, and generate liquidity. Loans Serviced for Others and Loan Securitization The Company generally retains the servicing rights of the guaranteed portion of SBA loans sold, for which the Company initially records a servicing asset at fair value within its other assets category. Servicing assets are subsequently measured using the amortization method and amortized to noninterest income. At June 30, 2024 and December 31, 2023, the servicing assets totaled $1.2 million and $1.6 million, respectively, and were included in other assets in the Company’s consolidated statement of financial condition. Servicing assets are evaluated for impairment based upon the fair value of the servicing rights as compared to carrying amount. Impairment is recognized through a valuation allowance, to the extent the fair value is less than the carrying amount. At June 30, 2024 and December 31, 2023, the Company determined that no valuation allowance was necessary. In connection with the acquisition of Opus Bank (“Opus”), the Company acquired Federal Home Loan Mortgage Corporation (“Freddie Mac”) guaranteed structured pass-through certificates, which were issued as a result of Opus’s securitization sale of $509 million in originated multifamily loans through a Freddie Mac-sponsored transaction in December 2016. The Company's continuing involvement includes sub-servicing responsibilities, general representations and warranties, and reimbursement obligations. Servicing responsibilities on loan sales generally include obligations to collect and remit payments of principal and interest, provide foreclosure services, manage payments of taxes and insurance premiums, and otherwise administer the underlying loans. In connection with the securitization transaction, Freddie Mac was designated as the master servicer and appointed the Company to perform sub-servicing responsibilities, which generally include the servicing responsibilities described above with the exception of the servicing of foreclosed or defaulted loans. The overall management, servicing, and resolution of defaulted loans and foreclosed loans are separately designated to the special servicer, a third-party institution that is independent of the master servicer and the Company. The master servicer has the right to terminate the Company in its role as sub-servicer and direct such responsibilities accordingly. To the extent the ultimate resolution of defaulted loans results in contractual principal and interest payments that are deficient, the Company is obligated to reimburse Freddie Mac for such amounts, not to exceed 10% of the original principal amount of the loans comprising the securitization pool at the closing date of December 23, 2016. The liability recorded for Company’s exposure to the reimbursement agreement with Freddie Mac was $345,000 as of June 30, 2024 and December 31, 2023. Loans sold and serviced for others are not included in the accompanying consolidated statements of financial condition. The unpaid principal balance of loans and participations serviced for others was $340.1 million at June 30, 2024 and $373.8 million at December 31, 2023, respectively. Included in those totals are multifamily loans transferred through securitization with Freddie Mac of $44.2 million and $48.0 million at June 30, 2024 and December 31, 2023, respectively, and SBA participations serviced for others of $232.4 million and $258.1 million at June 30, 2024 and December 31, 2023, respectively. Concentration of Credit Risk As of June 30, 2024, the Company’s loan portfolio was primarily collateralized by various forms of real estate and business assets located predominately in California. The Company’s loan portfolio contains concentrations of credit in multifamily, CRE non-owner-occupied, CRE owner-occupied, and C&I business loans. The Bank maintains policies approved by the Bank’s Board of Directors (the “Bank Board”) that address these concentrations and diversifies its loan portfolio through loan originations, purchases, and sales to meet approved concentration levels. Under applicable laws and regulations, the Bank may not make secured loans to one borrower in excess of 25% of the Bank’s unimpaired capital plus surplus, and likewise in excess of 15% of the Bank’s unimpaired capital plus surplus for unsecured loans. These loans-to-one borrower limitations result in a dollar limitation of $845.0 million for secured loans and $507.0 million for unsecured loans at June 30, 2024. In order to manage concentration risk, the Bank maintains a house lending limit well below these statutory maximums. At June 30, 2024, the Bank’s largest aggregate outstanding balance of loans to one borrower was $229.5 million comprised of C&I asset-based lines of credit. Credit Quality and Credit Risk Management The Company’s credit quality and credit risk are controlled in two distinct areas. The first is the loan origination process, wherein the Bank underwrites credit and chooses which types and levels of risk it is willing to accept. The Company maintains a credit policy which addresses many related topics, sets forth maximum tolerances for key elements of loan risk, and indicates appropriate protocols for identifying and analyzing these risk elements. The policy sets forth specific guidelines for analyzing each of the loan products the Company offers from both an individual and portfolio-wide basis. The credit policy is reviewed at least annually by the Bank Board. The Bank’s underwriters ensure all key risk factors are analyzed, with most underwriting including a global cash flow analysis of the prospective borrowers. The second area is in the ongoing oversight of the loan portfolio, where existing credit risk is measured and monitored, and where performance issues are dealt with in a timely and appropriate fashion. Credit risk is monitored and managed within the loan portfolio by the Company’s portfolio managers based on both the credit policy and a credit and portfolio review policy. This latter policy requires a program of financial data collection and analysis, thorough loan reviews, property and/or business inspections, monitoring of portfolio concentrations and trends, and incorporation of current business and economic conditions. The portfolio managers also monitor asset-based lines of credit, loan covenants, and other conditions associated with the Company’s loans as a means to help identify potential credit risk. Most individual loans, excluding the homogeneous loan portfolio, are reviewed at least annually, including the assignment or confirmation of a risk grade. Risk grades are based on a six-grade Pass scale, along with Special Mention, Substandard, Doubtful, and Loss classifications, and such classifications are defined by the federal banking regulatory agencies. The assignment of risk grades allows the Company to, among other things, identify the risk associated with each credit in the portfolio and to provide a basis for estimating credit losses inherent in the portfolio. Risk grades are reviewed regularly with the Company’s Credit and Portfolio Review Committee, and the portfolio management and risk grading process is reviewed on an ongoing basis by both an independent loan review function and periodic internal audits, as well as by regulatory agencies during scheduled examinations. The following provides brief definitions for risk grades assigned to loans in the portfolio: • Pass assets carry an acceptable level of credit quality that contains no well-defined deficiencies or weaknesses. • Special Mention assets do not currently expose the Bank to a sufficient risk to warrant classification in one of the adverse categories, but possess correctable deficiencies or potential weaknesses deserving management’s close attention. • Substandard assets are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. These assets are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Other real estate owned (“OREO”) acquired through foreclosure is also classified as substandard. • Doubtful assets have all the weaknesses inherent in substandard assets, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. • Loss assets are those that are considered uncollectible and of such little value that their continuance as assets is not warranted. Amounts classified as loss are promptly charged off. The Bank’s portfolio managers also manage loan performance risks, collections, workouts, bankruptcies, and foreclosures. A special department, whose portfolio managers have professional expertise in these areas, typically handles or advises on these types of matters. Loan performance risks are mitigated by our portfolio managers acting promptly and assertively to address problem credits when they are identified. Collection efforts commence immediately upon non-payment, and the portfolio managers seek to promptly determine the appropriate steps to minimize the Company’s risk of loss. When foreclosure will maximize the Company’s recovery for a non-performing loan, the portfolio managers will take appropriate action to initiate the foreclosure process. When a loan is graded as special mention, substandard, or doubtful, the Company obtains an updated valuation of the underlying collateral. Collateral generally consists of accounts receivable, inventory, fixed assets, real estate properties, and/or cash. If, through the Company’s credit risk management process, it is determined the ultimate repayment of a loan will come from the foreclosure upon and ultimate sale of the underlying collateral, the loan is deemed collateral dependent and evaluated individually to determine an appropriate ACL for the loan. The ACL for such loans is measured as the amount by which the fair value of the underlying collateral, less estimated costs to sell, is less than the amortized cost of the loan. The Company typically continues to obtain or confirm updated valuations of underlying collateral for special mention and classified loans on an annual or biennial basis in order to have the most current indication of fair value of the underlying collateral securing the loan. Additionally, once a loan is identified as collateral dependent, due to the likelihood of foreclosure, and repayment of the loan is expected to come from the eventual sale of the underlying collateral, an analysis of the underlying collateral is performed at least quarterly. Changes in the estimated fair value of the collateral are reflected in the lifetime ACL for the loan. Balances deemed to be uncollectable are promptly charged-off. However, if a loan is not considered collateral dependent and management determines that the loan no longer possesses risk characteristics similar to other loans in the loan portfolio, the loan is individually evaluated, and the associated ACL is determined through the use of a discounted cash flow analysis.

Refer to Note 11 – Derivative Instruments for additional information. (2) Nonaccrual loans are included in this aging analysis based on the loan’s past due status. Individually Evaluated Loans The Company evaluates loans collectively for purposes of determining the ACL in accordance with ASC 326. Collective evaluation is based on aggregating loans deemed to possess similar risk characteristics. In certain instances, the Company may identify loans that it believes no longer possess risk characteristics similar to other loans in the portfolio. These loans are typically identified from a substandard or worse internal risk grade, since the specific attributes and risks associated with such loans tend to become unique as the credit deteriorates. Such loans are typically nonperforming, modified loans made to borrowers experiencing financial difficulty, and/or are deemed collateral dependent, where the ultimate repayment of the loan is expected to come from the operation of or eventual sale of the collateral. Loans that are deemed by management to no longer possess risk characteristics similar to other loans in the portfolio are evaluated individually for purposes of determining an appropriate lifetime ACL. The Company uses a discounted cash flow approach, using the loan’s effective interest rate, for determining the ACL on individually evaluated loans, unless the loan is deemed collateral dependent, which requires evaluation based on the estimated fair value of the underlying collateral, less estimated costs to sell. The Company may increase or decrease the ACL for collateral dependent individually evaluated loans based on changes in the estimated expected fair value of the collateral. Changes in the ACL for all other individually evaluated loans is based substantially on the Company’s evaluation of cash flows expected to be received from such loans. As of June 30, 2024, $52.1 million of loans were individually evaluated with a $237,000 ACL attributed to such loans. At June 30, 2024, $38.5 million of individually evaluated loans were evaluated based on the underlying value of the collateral, and $13.6 million were evaluated using a discounted cash flow approach. All individually evaluated loans were on nonaccrual status at June 30, 2024. As of December 31, 2023, $24.8 million of loans were individually evaluated with no ACL attributed to such loans. At December 31, 2023, $12.2 million of individually evaluated loans were evaluated based on the underlying value of the collateral, and $12.6 million were evaluated using a discounted cash flow approach. All individually evaluated loans were on nonaccrual status at December 31, 2023. The increase in individually evaluated loans during the first half of 2024 was primarily driven by a single, diversified commercial banking relationship with loans in CRE non-owner-occupied and C&I categories, totaling $26.1 million as of June 30, 2024. Purchased Credit Deteriorated Loans The Company analyzed acquired loans for more-than-insignificant deterioration in credit quality since their origination. Such loans are classified as purchased credit deteriorated (“PCD”) loans. Please see Note 1 - Description of Business and Summary of Significant Accounting Policies of our audited consolidated financial statements included in our 2023 Form 10-K for more information concerning the accounting for PCD loans. The Company had PCD loans of $328.0 million and $359.3 million at June 30, 2024 and December 31, 2023, respectively. Acquired loans classified as PCD are recorded at an initial amortized cost, which is comprised of the purchase price of the loans (or initial fair value) and the initial ACL determined for the loans, which is added to the purchase price, as well as any resulting discount or premium related to factors other than credit. The Company accounts for interest income on PCD loans using the interest method, whereby any purchase discounts or premiums are accreted or amortized into interest income as an adjustment of the loan’s yield. Subsequent to acquisition, the ACL for PCD loans is measured in accordance with the Company’s ACL methodology. Please also see Note 6 – Allowance for Credit Losses for more information concerning the Company’s ACL methodology. Nonaccrual Loans When loans are placed on nonaccrual status, previously accrued but unpaid interest is reversed from current period earnings. Payments received on nonaccrual loans are generally applied as a reduction to the loan principal balance. If the likelihood of further loss is remote, the Company may recognize interest on a cash basis. Loans may be returned to accruing status if the Company believes that all remaining principal and interest is fully collectible and there has been at least three months of sustained repayment performance since the loan was placed on nonaccrual. The Company typically does not accrue interest on loans 90 days or more past due or when, in the opinion of management, there is reasonable doubt as to the timely collection of principal or interest regardless of the length of past due status. However, when such loans are well-secured and in the process of collection, the Company may continue with the accrual of interest. The Company had loans on nonaccrual status of $52.1 million at June 30, 2024 and $24.8 million at December 31, 2023. The increase in nonaccrual loans at June 30, 2024 was primarily the result of a single, diversified commercial banking relationship with loans in CRE non-owner occupied and C&I categories, totaling $26.1 million, all of which were current as of June 30, 2024.

Allowance for Credit Loss [Abstract]
Allowance for Credit Losses	Allowance for Credit Losses The Company maintains an ACL for loans and unfunded loan commitments in accordance with ASC 326 - Financial Instruments - Credit Losses . ASC 326 requires the Company to initially recognize estimates for lifetime credit losses on loans and unfunded loan commitments at the time of origination or acquisition. The recognition of credit losses represents the Company’s best estimate of lifetime expected credit losses, given the facts and circumstances associated with a particular loan or group of loans with similar risk characteristics. Determining the ACL involves the use of significant management judgement and estimates, which are subject to change based on management’s ongoing assessment of the credit quality of the loan portfolio and changes in economic forecasts used in the Company’s ACL model. The Company uses a discounted cash flow model when determining estimates for the ACL for commercial real estate loans and commercial loans, which comprise the majority of the loan portfolio, and uses a historical loss rate model for retail loans. The Company also utilizes proxy loan data in its ACL model where the Company’s own historical data is not sufficiently available. The discounted cash flow model is applied on an instrument-by-instrument basis, and for loans with similar risk characteristics, to derive estimates for the lifetime ACL for each loan. The discounted cash flow methodology relies on several significant components essential to the development of estimates for future cash flows on loans and unfunded loan commitments. These components consist of: (i) the estimated probability of default (“PD”), (ii) the estimated loss given default (“LGD”), which represents the estimated severity of the loss when a loan is in default, (iii) estimates for prepayment activity on loans, and (iv) the estimated exposure to the Company at default (“EAD”). The PD and LGD are heavily influenced by changes in economic forecasts employed in the model over a reasonable and supportable period. The Company’s ACL methodology for unfunded loan commitments also includes assumptions concerning the probability an unfunded commitment will be drawn upon by the borrower. These assumptions are based on the Company’s historical experience. The Company’s discounted cash flow ACL model for CRE and commercial loans uses internally derived estimates for prepayments in determining the amount and timing of future contractual cash flows expected to be collected. The estimate of future cash flows also incorporates estimates for contractual amounts the Company believes may not be collected, which are based on assumptions for PD, LGD, and EAD. The EAD is determined by the contractual payment schedule and expected payment profile of the loan, incorporating estimates for expected prepayments and future draws on revolving credit facilities. The Company discounts cash flows using the effective interest rate on the loan. The effective interest rate represents the contractual rate on the loan; adjusted for any purchase premiums, or discounts, and deferred fees and costs associated with an originated loan. The Company has made an accounting policy election to adjust the effective interest rate to take into consideration the effects of estimated prepayments. The ACL for loans is determined by measuring the amount by which a loan’s amortized cost exceeds its discounted cash flows expected to be collected. The ACL for credit facilities is determined by discounting estimates for cash flows not expected to be collected. Probability of Default The PD for investor loans secured by real estate is based largely on a model provided by a third party, using proxy loan information. The PDs generated by this model are reflective of current and expected economic conditions in the commercial real estate market, and how they are expected to impact loan level and property level attributes, and ultimately the likelihood of a default event occurring. This model incorporates assumptions for PD at a loan’s maturity. Significant loan and property level attributes include: loan-to-value ratios, debt service coverage, loan size, loan vintage, and property types. The PD for business loans secured by real estate and commercial loans is based on an internally developed PD rating scale that assigns PDs based on the Company’s internal credit risk grades for loans. This internally developed PD rating scale is based on a combination of the Company’s own historical data and observed historical data from the Company’s peers, which consist of banks that management believes align with our business profile. As credit risk grades change for these loans, the PD assigned to them also changes. As with investor loans secured by real estate, the PD for business loans secured by real estate and commercial loans is also impacted by current and expected economic conditions. The Company considers loans to be in default when they are 90 days or more past due or placed on nonaccrual status. Loss Given Default LGDs for commercial real estate loans are derived from a third party, using proxy loan information, and are based on loan and property level characteristics for loans in the Company’s loan portfolio, such as: loan-to-value ratios (“LTV”), estimated time to resolution, property size, and current and estimated future market price changes for underlying collateral. The LGD is highly dependent upon LTV ratios, and incorporates estimates for the expense associated with managing the loan through to resolution. LGDs also incorporate an estimate for the loss severity associated with loans where the borrower fails to meet their debt obligation at maturity, such as through a balloon payment or the refinancing of the loan through another lender. External factors that have an impact on LGDs include: changes in the index for CRE pricing, GDP growth rate, unemployment rates, and the Consumer Price Index. LGDs are applied to each loan in the commercial real estate portfolio, and in conjunction with the PD, produce estimates for net cash flows not expected to be collected over the estimated term of the loan. LGDs for commercial loans are also derived from a third party that has a considerable database of credit related information specific to the financial services industry and the type of loans within this segment, and is used to generate annual default information for commercial loans. These proxy LGDs are dependent upon data inputs such as: credit quality, borrower industry, region, borrower size, and debt seniority. LGDs are then applied to each loan in the commercial segment, and in conjunction with the PD, produce estimates for net cash flows not expected to be collected over the estimated term of the loan. Historical Loss Rates for Retail Loans The historical loss rate model for retail loans is derived from a third party that has a considerable database of credit related information for retail loans. Key loan level attributes and economic drivers in determining the loss rate for retail loans include FICO scores, vintage, as well as geography, unemployment rates, and changes in consumer real estate prices. Economic Forecasts In order to develop reasonable and supportable forecasts of future conditions, the Company estimates how those forecasts are expected to impact a borrower’s ability to satisfy their obligation to the Bank and the ultimate collectability of future cash flows over the life of a loan. The Company uses macroeconomic scenarios from an independent third party, which are based on past events, current conditions, and the likelihood of future events occurring. These scenarios are typically comprised of: a base-case scenario, an upside scenario, representing slightly better economic conditions than currently experienced and, a downside scenario, representing recessionary conditions. Management periodically evaluates appropriateness of economic scenarios and may decide that a particular economic scenario or a combination of probability-weighted economic scenarios should be used in the Company’s ACL model. The economic scenarios chosen for the model, the extent to which more than one scenario is used, and the weights that are assigned to them, are based on the likelihood that the economy would perform better than each scenario, which is based in part on analysis performed by an independent third party. Economic scenarios chosen, as well as the assumptions within those scenarios, and whether to use a probability-weighted multiple scenario approach, can vary from one period to the next based on changes in current and expected economic conditions, and due to the occurrence of specific events. The Company’s ACL model at June 30, 2024 includes assumptions concerning the interest rate environment, general uncertainty concerning future economic conditions, and the potential for recessionary conditions. The Company currently forecasts PDs and LGDs based on economic scenarios over a two-year period, which we believe is a reasonable and supportable period. Beyond this point, PDs and LGDs revert to their long-term averages. The Company has reflected this reversion over a period of three years in each of its economic scenarios used to generate the overall probability-weighted forecast. Changes in economic forecasts impact the PD, LGD, and EAD for each loan, and therefore influence the amount of future cash flows the Company does not expect to collect for each loan. It is important to note that the Company’s ACL model relies on multiple economic variables, which are used in several economic scenarios. Although no one economic variable can fully demonstrate the sensitivity of the ACL calculation to changes in the economic variables used in the model, the Company has identified certain economic variables that have significant influence in the Company’s model for determining the ACL. These key economic variables include changes in the U.S. unemployment rate, U.S. real GDP growth, CRE prices, and interest rates. Qualitative Adjustments The Company recognizes that historical information used as the basis for determining future expected credit losses may not always, by itself, provide a sufficient basis for determining future expected credit losses. The Company, therefore, considers the need for qualitative adjustments to the ACL on a quarterly basis. Qualitative adjustments may be related to and include, but not be limited to, factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through back-testing, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios, and changes in portfolio segmentation, and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. Qualitative adjustments primarily relate to certain segments of the loan portfolio deemed by management to be of a higher-risk profile or other factors where management believes the quantitative component of the Company’s ACL model may not be fully reflective of levels deemed adequate in the judgement of management. Certain qualitative adjustments also relate to heightened uncertainty as to future macroeconomic conditions and the related impact on certain loan segments. Management reviews the need for an appropriate level of qualitative adjustments on a quarterly basis, and as such, the amount and allocation of qualitative adjustments may change in future periods. The following tables provide the allocation of the ACL for loans held for investment as well as the activity in the ACL attributed to various segments in the loan portfolio as of, and for the periods indicated: Three Months Ended June 30, 2024 (Dollars in thousands) Beginning ACL Balance Charge-offs Recoveries Provision for Credit Losses Ending ACL Balance Investor loans secured by real estate CRE non-owner-occupied $ 30,781 $ (4,196) $ 1,500 $ 1,653 $ 29,738 Multifamily 58,411 (7,372) — 6,259 57,298 Construction and land 8,171 — — 2,633 10,804 SBA secured by real estate 2,184 (153) 86 25 2,142 Business loans secured by real estate CRE owner-occupied 28,760 — 121 (350) 28,531 Franchise real estate secured 7,258 — — (464) 6,794 SBA secured by real estate 4,288 — 1 (155) 4,134 Commercial loans Commercial and industrial 37,107 (968) 148 (4,030) 32,257 Franchise non-real estate secured 14,320 — 1,375 (4,565) 11,130 SBA non-real estate secured 495 (6) 3 (10) 482 Retail loans Single family residential 442 — 3 (46) 399 Consumer loans 123 (835) — 806 94 Totals $ 192,340 $ (13,530) $ 3,237 $ 1,756 $ 183,803 Six Months Ended June 30, 2024 Beginning ACL Balance Charge-offs Recoveries Provision for Credit Losses Ending (Dollars in thousands) Investor loans secured by real estate CRE non-owner occupied $ 31,030 $ (5,123) $ 1,500 $ 2,331 $ 29,738 Multifamily 56,312 (7,372) 5 8,353 57,298 Construction and land 9,314 — — 1,490 10,804 SBA secured by real estate 2,182 (406) 86 280 2,142 Business loans secured by real estate CRE owner-occupied 28,787 (4,452) 184 4,012 28,531 Franchise real estate secured 7,499 (212) — (493) 6,794 SBA secured by real estate 4,427 — 2 (295) 4,134 Commercial loans Commercial and industrial 36,692 (1,553) 187 (3,069) 32,257 Franchise non-real estate secured 15,131 (100) 1,375 (5,276) 11,130 SBA non-real estate secured 458 (6) 5 25 482 Retail loans Single family residential 505 — 3 (109) 399 Consumer loans 134 (835) — 795 94 Totals $ 192,471 $ (20,059) $ 3,347 $ 8,044 $ 183,803 Three Months Ended June 30, 2023 (Dollars in thousands) Beginning ACL Balance Charge-offs Recoveries Provision for Credit Losses Ending Investor loans secured by real estate CRE non-owner-occupied $ 31,715 $ (2,591) $ — $ 2,421 $ 31,545 Multifamily 57,787 (73) 1 (2,067) 55,648 Construction and land 7,672 — — 35 7,707 SBA secured by real estate 2,291 — — 40 2,331 Business loans secured by real estate CRE owner-occupied 29,334 (207) 12 (624) 28,515 Franchise real estate secured 7,790 — — (935) 6,855 SBA secured by real estate 4,415 — 80 16 4,511 Commercial loans Commercial and industrial 37,659 (225) 169 1,983 39,586 Franchise non-real estate secured 15,721 — — (1,079) 14,642 SBA non-real estate secured 401 — 59 (61) 399 Retail loans Single family residential 392 — — 63 455 Consumer loans 211 (890) — 818 139 Totals $ 195,388 $ (3,986) $ 321 $ 610 $ 192,333 Six Months Ended June 30, 2023 (Dollars in thousands) Beginning ACL Balance Charge-offs Recoveries Provision for Credit Losses Ending Investor loans secured by real estate CRE non-owner occupied $ 33,692 $ (2,657) $ 15 $ 495 $ 31,545 Multifamily 56,334 (290) 1 (397) 55,648 Construction and land 7,114 — — 593 7,707 SBA secured by real estate 2,592 — — (261) 2,331 Business loans secured by real estate CRE owner-occupied 32,340 (2,370) 24 (1,479) 28,515 Franchise real estate secured 7,019 — — (164) 6,855 SBA secured by real estate 4,348 — 80 83 4,511 Commercial loans Commercial and industrial 35,169 (1,348) 380 5,385 39,586 Franchise non-real estate secured 16,029 — 100 (1,487) 14,642 SBA non-real estate secured 441 — 65 (107) 399 Retail loans Single family residential 352 (90) 1 192 455 Consumer loans 221 (895) 35 778 139 Totals $ 195,651 $ (7,650) $ 701 $ 3,631 $ 192,333 The decrease in the ACL for loans held for investment during the three months ended June 30, 2024 of $8.5 million was reflective of $10.3 million in net charge-offs, partially offset by $1.8 million in provision for credit losses. During the six months ended June 30, 2024, the ACL for loans held for investment decreased $8.7 million, which was reflective of $16.7 million in net charge-offs, partially offset by $8.0 million in provision for credit losses. The provision for credit losses during the three and six months ended June 30, 2024 was largely attributed to increases associated with economic forecasts, which reflect changes in the CRE market overall, and other model updates, offset by a decrease in the balance of loans held of investment, changes in loan composition, and changes in asset quality. Charge-offs during the three months ended June 30, 2024 were largely due to $11.5 million in charge-offs related to the sale of a substandard multifamily loan and a substandard non-owner-occupied CRE loan during the second quarter of 2024. For the six months ended June 30, 2024, charge-offs were largely attributed to the charge-offs recorded in the second quarter of 2024 as well as $5.7 million in charge-offs associated with the sale of special mention and substandard CRE and franchise loans during the first quarter of 2024. The decrease in the ACL for loans held for investment during the three months ended June 30, 2023 of $3.1 million was reflective of $3.7 million in net charge-offs, partially offset by $610,000 in provision for credit losses. The provision for credit losses during the three months ended June 30, 2023 was largely attributed to increases associated with economic forecasts, offset by a decrease in the balance of loans held for investment. For the six months ended June 30, 2023, the ACL decreased $3.3 million. The decline in the ACL during this period was reflective of $6.9 million in net charge-offs, partially offset by $3.6 million in provision for credit losses. The provision for credit losses during the six months ended June 30, 2023 was largely attributed to increases associated with economic forecasts, as well as changes in asset quality, including specific reserves, offset by a decrease in loans held for investment. Charge-offs during the three months ended June 30, 2023 were largely attributed to one CRE non-owner occupied lending relationship and charge-offs in consumer loans. Charge-offs during the six months ended June 30, 2023 were largely attributed to one CRE non-owner occupied lending relationship and one CRE owner-occupied lending relationship. Allowance for Credit Losses for Off-Balance Sheet Commitments The Company maintains an ACL for off-balance sheet commitments related to unfunded loans and lines of credit, which is included in other liabilities of the consolidated statements of financial condition. The allowance for off-balance sheet commitments was $16.3 million at June 30, 2024, a decline of $505,000 from $16.8 million at March 31, 2024, and a decrease of $2.9 million from December 31, 2023. During the three months ended June 30, 2024, the provision recapture for off-balance sheet commitments was largely attributable to slightly lower loss rates for C&I loans, partially offset by a slight increase in the balance of unfunded commitments during the quarter. The provision recapture for off-balance sheet commitments during the six months ended June 30, 2024 was attributed largely to overall lower levels of unfunded commitments during the period. During the three months ended June 30, 2023, the provision expense for off-balance sheet commitments of $1.0 million was attributable to higher loss rates in certain segments of the loan portfolio, partially offset by a decline in the balance of unfunded commitments. The provision expense during the six months ended June 30, 2023 was largely attributed to higher loss rates in certain loan segments, partially offset by changes in the mix of unfunded commitments between various loan segments, and a decrease in the balance of unfunded commitments. The following table summarizes the activities in the ACL for off-balance sheet commitments for the periods indicated: Three Months Ended Six Months Ended June 30, June 30, June 30, June 30, (Dollars in thousands) 2024 2023 2024 2023 Beginning ACL balance $ 16,839 $ 23,452 $ 19,264 $ 23,641 Provision for credit losses on off-balance sheet commitments (505) 1,003 (2,930) 814 Ending ACL balance $ 16,334 $ 24,455 $ 16,334 $ 24,455

KBRA assigned investment grade ratings of BBB+ and BBB for the Corporation’s senior unsecured debt and subordinated debt, respectively, and a deposit and senior unsecured debt rating of A- and subordinated debt of BBB+ for the Bank. The Corporation’s and Bank’s ratings were reaffirmed in May 2024 by KBRA. For additional information on the Company’s subordinated debentures, see “ Note 13 — Subordinated Debentures ” to the audited consolidated financial statements in the Company’s 2023 Form 10-K. For regulatory capital purposes, subordinated notes qualify as Tier 2 capital, subject to limitations. Per applicable Federal Reserve rules and regulations, the amount of the subordinated notes qualifying as Tier 2 regulatory capital is phased out by 20% of the original amount of the subordinated notes in each of the five years beginning on the fifth anniversary preceding the maturity date of the subordinated notes. The regulatory total capital ratios of the Company and the Bank continued to exceed regulatory minimums, inclusive of the fully phased-in capital conservation buffer.

Earnings Per Share

Earnings Per Share	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share The Company’s restricted stock awards contain non-forfeitable rights to dividends and therefore are considered participating securities. The Company calculates basic and diluted earnings per common share using the two-class method. Under the two-class method, distributed and undistributed earnings allocable to participating securities are deducted from net income to determine net income allocable to common shareholders, which is then used in the numerator of both basic and diluted earnings per share calculations. Basic earnings per common share is computed by dividing net income allocable to common shareholders by the weighted average number of common shares outstanding for the reporting period, excluding outstanding participating securities. Diluted earnings per common share is computed by dividing net income allocable to common shareholders by the weighted average number of common shares outstanding over the reporting period, adjusted to include the effect of potentially dilutive common shares, but excludes awards considered participating securities. The computation of diluted earnings per common share excludes the impact of the assumed exercise or issuance of securities that would have an anti-dilutive effect.

Fair Value of Financial Instrum

Fair Value of Financial Instruments	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value of an asset or liability is the exchange price that would be received to sell that asset or paid to transfer that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 825 - Financial Instruments , requires disclosure of the fair value of financial assets and financial liabilities, including both those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis and a non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value are discussed below. In accordance with ASC Topic 820 - Fair Value Measurement , the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. 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 instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, volatilities, etc.), or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market. Level 3 - Valuation is generated from model-based techniques where one or more significant inputs are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of matrix pricing, discounted cash flow models, and similar techniques. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent limitations in any estimation technique. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following is a description of both the general and specific valuation methodologies used for certain instruments measured at fair value, as well as the general classification of these instruments pursuant to the fair value hierarchy. AFS Investment Securities – Investment securities are generally valued based upon quotes obtained from independent third-party pricing services, which use evaluated pricing applications and model processes. Observable market inputs, such as, benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data are considered as part of the evaluation. The inputs are related directly to the security being evaluated, or indirectly to a similarly situated security. Market assumptions and market data are utilized in the valuation models. The Company reviews the market prices provided by the third-party pricing service for reasonableness based on the Company’s understanding of the marketplace and credit issues related to the securities. The Company has not made any adjustments to the market quotes provided by them and, accordingly, the Company categorized these securities within Level 2 of the fair value hierarchy. Equity Securities With Readily Determinable Fair Values – The Company’s equity securities with readily determinable fair values consist of investments in public companies and qualify for CRA purposes. The fair value is based on the closing price on nationally recognized securities exchanges at the end of each period and classified as Level 1 of the fair value hierarchy. Interest Rate Swaps – The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back swap agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The Company also enters into interest rate swap contracts with institutional counterparties to hedge against certain fixed-rate loans. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a market standard discounted cash flow approach. The Company incorporates credit value adjustments on derivatives to properly reflect the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. The Company has determined that the observable nature of the majority of inputs used in deriving the fair value of these derivative contracts fall within Level 2 of the fair value hierarchy, and the credit valuation adjustments are not significant to the overall valuation of its derivative financial instruments. As a result, the valuation of interest rate swaps is classified as Level 2 of the fair value hierarchy. Equity Warrant Assets – The Company acquired equity warrant assets as a result of the acquisition of Opus. The warrants provide the Bank the right to purchase a specific number of equity shares of the underlying company’s equity at a certain price before expiration and contain net settlement terms qualifying as derivatives under ASC Topic 815 - Derivatives and Hedging . The fair value of equity warrant assets is determined using a Black-Scholes option pricing model and are classified as Level 3 within the fair value hierarchy due to the extent of unobservable inputs. The key assumptions used in determining the fair value include the exercise price of the warrants, valuation of the underlying entity's outstanding stock, expected term, risk-free interest rate, marketability discount for private company warrants, and price volatility. During 2023, the equity warrant assets were either settled or written off as the warrants were determined to not be exercisable until the underlying company’s fair market value is greater than the value established in the warrant agreement. Foreign Exchange Contracts – The Company enters into foreign exchange contracts to accommodate the business needs of its customers. The Company also enters into offsetting contracts with institutional counterparties to mitigate the Company’s foreign exchange exposure with its customers, or enters into bilateral collateral and master netting agreements with certain customer counterparties to manage its credit exposure. The Company measures the fair value of foreign exchange contracts based on quoted prices for identical instruments in active markets, a Level 1 measurement.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Individually Evaluated Loans – A loan is individually evaluated for expected credit losses when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement and it does not share similar risk characteristics with other loans. Individually evaluated loans are measured at fair value when they are deemed collateral dependent. Fair value on such loans is measured based on the underlying collateral. Collateral generally consists of accounts receivable, inventory, fixed assets, real estate, and cash. The Company measures impairment on all individually evaluated loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling costs. Other Real Estate Owned – OREO is initially recorded at the fair value less estimated costs to sell at the date of transfer. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the allowance for credit losses. The fair value of individually evaluated collateral dependent loans and OREO were determined using Level 3 assumptions, and represents individually evaluated loan for which a specific reserve has been established or on which a write down has been taken. For real estate loans, generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its individually evaluated loans to determine fair value. In determining the net realizable value of the underlying collateral for individually evaluated loans and OREO, the Company then discounts the valuation to cover both market price fluctuations and selling costs, typically ranging from 7% to 10% of the collateral value, that the Company expects would be incurred in the event of foreclosure. In addition to the discounts taken, the Company’s calculation of net realizable value considered any other senior liens in place on the underlying collateral. For non-real estate loans, fair value of the loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions, and management’s expertise and knowledge of the client and client’s business. At June 30, 2024, the Company’s individually evaluated collateral dependent loans were evaluated based on the fair value of their underlying collateral based upon the most recent appraisals available to management. The Company completed partial charge-offs on certain individually evaluated loans based on recent real estate or property appraisals and recorded the related reserves where applicable during the six months ended June 30, 2024.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments The Company uses derivative instruments to manage its exposure to market risks, including interest rate risk, and to assist customers with their risk management objectives. The Company designates certain derivatives as hedging instruments in a qualifying hedge accounting relationship, while other derivatives serve as economic hedges that do not qualify for hedge accounting. Derivatives Designated as Hedging Instruments Fair Value Hedges – The Company is exposed to changes in the fair value of fixed-rate assets due to changes in benchmark interest rates. The Company entered into pay-fixed and receive-floating interest rate swaps associated with certain fixed rate loans, primarily multifamily and commercial real estate loans, to manage its exposure to changes in fair value on these instruments attributable to changes in the designated SOFR benchmark interest rate. These interest rate swaps are designated as fair value hedges using the portfolio layer method. The Company receives variable-rate interest payments in exchange for making fixed-rate payments over the lives of the contracts without exchanging the notional amounts. The fair value hedges are recorded as components of other assets and other liabilities in the Company’s consolidated statements of financial condition. The gain or loss on these derivatives, as well as the offsetting loss or gain on the hedged items attributable to the hedged risk, are recognized consistent with the classification of the hedged item in interest income in the Company’s consolidated statements of income. At June 30, 2024 and December 31, 2023, interest rate swaps with an aggregate notional amount of $1.35 billion and $1.35 billion respectively, were designated as fair value hedges. The following amounts were recorded on the consolidated statement of financial condition related to cumulative basis adjustment for fair value hedges as of the dates indicated: Line Item in the Statement of Financial Position in Which the Hedged Item is Included Carrying Amount of the Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Assets (Dollars in thousands) June 30, 2024 December 31, 2023 June 30, 2024 December 31, 2023 Loans held for investment (1) $ 1,321,799 $ 1,320,449 $ (28,201) $ (29,551) Total $ 1,321,799 $ 1,320,449 $ (28,201) $ (29,551) ______________________________ (1) These amounts were included in the amortized cost basis of closed portfolios of loans held for investment used to designate hedging relationships in which the hedged item is the stated amount of assets in the closed portfolios anticipated to be outstanding for the designated hedge period. At June 30, 2024 and December 31, 2023, the amortized cost basis of the closed portfolios used in these hedging relationships was $3.13 billion and $3.25 billion, respectively, the cumulative basis adjustments associated with these hedging relationships was $(28.2) million and $(29.6) million, respectively, and the amounts of the designated hedged items were $1.35 billion and $1.35 billion, respectively. Derivatives Not Designated as Hedging Instruments Interest Rate Swap Contracts – From time to time, the Company enters into interest rate swap agreements with certain borrowers to assist them in mitigating their interest rate risk exposure associated with the loans they have with the Company. At the same time, the Company enters into identical offsetting interest rate swap agreements with another financial institution to mitigate the Company’s interest rate risk exposure associated with the swap agreements it enters into with its borrowers. The Company has over-the-counter derivative instruments and centrally-cleared derivative instruments with matched terms. The fair values of these agreements are determined through a third-party valuation model used by the Company’s swap advisory firm, which uses observable market data such as interest rates, prices of Eurodollar futures contracts, and market swap rates. The fair values of these swaps are recorded as components of other assets and other liabilities in the Company’s consolidated statement of financial condition. Changes in the fair value of these swaps, which occur due to changes in interest rates, are recorded in the Company’s statement of income as a component of noninterest income. Upon the cessation of LIBOR on June 30, 2023, our LIBOR-indexed interest rate swap contracts transitioned to SOFR as successor rate for both valuations and settlements. Over-the-counter contracts are tailored to meet the needs of the counterparties involved and, therefore, generally contain a greater degree of credit risk and liquidity risk than centrally-cleared contracts, which have standardized terms. Although changes in the fair value of swap agreements between the Company and borrowers and the Company and other financial institutions offset each other, changes in the credit risk of these counterparties may result in a difference in the fair value of the swap agreements. Offsetting over-the-counter swap agreements the Company has with other financial institutions are collateralized with cash, and swap agreements with borrowers are secured by the collateral arrangements for the underlying loans these borrowers have with the Company. All interest rate swap agreements entered into by the Company are free-standing derivatives and are not designated as hedging instruments. Foreign Exchange Contracts – The Company offers foreign exchange spot and forward contracts as accommodations to its customers to purchase and/or sell foreign currencies at a contractual price. In conjunction with these products the Company also enters into offsetting contracts with institutional counterparties to mitigate the Company’s foreign exchange exposure with its customers, or enters into bilateral collateral and master netting agreements with certain customer counterparties to manage its credit exposure. These contracts allow the Company to offer its customers foreign exchange products while minimizing its exposure to foreign exchange rate fluctuations. These foreign exchange contracts are not designated as hedging instruments and are recorded at fair value in other assets and other liabilities in the Company’s consolidated statements of financial condition. Changes in the fair value of these contracts are recorded in the Company’s consolidated statements of income as a component of noninterest income. Equity Warrant Assets – The Company acquired equity warrant assets as a result of the acquisition of Opus. The warrants provide the Bank the right to purchase a specific number of equity shares of the underlying company’s equity at a certain price before expiration and contain net settlement terms qualifying as derivatives under ASC Topic 815. Changes in the fair value of the warrants are recognized as a component of noninterest income with a corresponding offset within other assets. The total fair value of the warrants held in private companies was zero in other assets as of June 30, 2024 and December 31, 2023. During 2023, the equity warrant assets were either settled or written off as the warrants were determined to not be exercisable until the underlying company’s fair market value is greater than the value established in the warrant agreement.

Offsetting [Abstract]
Balance Sheet Offsetting	Balance Sheet Offsetting Derivative financial instruments may be eligible for offset in the consolidated statements of financial condition, such as those subject to enforceable master netting arrangements or a similar agreement. Under these agreements, the Company has the right to net settle multiple contracts with the same counterparty. The Company offers an interest rate swap product to qualified customers, which are then paired with derivative contracts the Company enters into with a counterparty bank. While derivative contracts entered into with counterparty banks may be subject to enforceable master netting agreements, derivative contracts with customers may not be subject to enforceable master netting arrangements. With regard to derivative contracts not centrally cleared through a clearinghouse, regulations require collateral to be posted by the party with a net liability position. Parties to a centrally cleared over-the-counter derivative exchange daily payments that reflect the daily change in the value of the derivative.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Variable Interest Entities The Company is involved with VIEs through its loan securitization activities and affordable housing investments that qualify for the low-income housing tax credit (“LIHTC”). The Company has determined that its interests in these entities meet the definition of variable interests. As of June 30, 2024 and December 31, 2023, the Company determined it was not the primary beneficiary of the VIEs and did not consolidate its interests in VIEs. The following table provides a summary of the carrying amount of assets and liabilities in the Company’s consolidated statements of financial condition and maximum exposure to loss as of June 30, 2024 and December 31, 2023 that relate to variable interests in non-consolidated VIEs. June 30, 2024 December 31, 2023 (Dollars in thousands) Maximum Loss Assets Liabilities Maximum Loss Assets Liabilities Multifamily loan securitization: Investment securities (1) $ 44,233 $ 44,233 $ — $ 48,204 $ 48,204 $ — Reimbursement obligation (2) 44,239 — 345 47,994 — 345 Affordable housing partnership: Other investments (3) 51,547 81,885 — 57,016 89,085 — Unfunded equity commitments (2) — — 30,338 — — 32,070 Total $ 140,019 $ 126,118 $ 30,683 $ 153,214 $ 137,289 $ 32,415 ______________________________ (1) Included in investment securities AFS on the consolidated statement of financial condition. (2) Included in accrued expenses and other liabilities on the consolidated statement of financial condition. (3) Included in other assets on the consolidated statement of financial condition. Multifamily Loan Securitization With respect to the securitization transaction with Freddie Mac discussed in Note 5 – Loans Held for Investment , the Company’s variable interests reside with the underlying Freddie Mac-issued guaranteed, structured pass-through certificates that were held as AFS investment securities at fair value as of June 30, 2024. Additionally, the Company has variable interests through a reimbursement agreement executed by Freddie Mac that obligates the Company to reimburse Freddie Mac for any defaulted contractual principal and interest payments identified after the ultimate resolution of the defaulted loans. Such reimbursement obligations are not to exceed 10% of the original principal amount of the loans comprising the securitization pool. As part of the securitization transaction, the Company released all servicing obligations and rights to Freddie Mac who was designated as the Master Servicer. In its capacity as Master Servicer, Freddie Mac can terminate the Company’s role as sub-servicer and direct such responsibilities accordingly. In evaluating our variable interests and continuing involvement in the VIE, we determined that we do not have the power to make significant decisions or direct the activities that most significantly impact the economic performance of the VIE’s assets and liabilities. As sub-servicer of the loans, the Company does not have the authority to make significant decisions that influence the value of the VIE’s net assets and, therefore, the Company is not the primary beneficiary of the VIE. As a result, we determined that the VIE associated with the multifamily securitization should not be included in the consolidated financial statements of the Company. We believe that our maximum exposure to loss as a result of our involvement with the VIE associated with the securitization is the carrying value of the investment securities issued by Freddie Mac and purchased by the Company. Additionally, our maximum exposure to loss under the reimbursement agreement executed with Freddie Mac is 10% of the original principal amount of the loans comprising the securitization pool, or $50.9 million. However, as the total outstanding principal amount of the underlying loans decreased below the aforementioned threshold, the maximum exposure declined to the total outstanding principal amount of the underlying loans of $44.2 million at June 30, 2024 and $48.0 million at December 31, 2023. Based upon our analysis of quantitative and qualitative data over the underlying loans included in the securitization pool, as of June 30, 2024 and December 31, 2023, our reserve for estimated losses with respect to the reimbursement obligation was $345,000. Investments in Qualified Affordable Housing Partnerships The Company has variable interests through its affordable housing partnership investments. These investments are fundamentally designed to provide a return through the generation of income tax credits and other income tax benefits. The Company has evaluated its involvement with the low-income housing projects and determined it does not have the ability to exercise significant influence over or participate in the decision-making activities related to the management of the projects, and therefore, is not the primary beneficiary, and does not consolidate these interests.

Income Tax Disclosure [Abstract]
Tax Equity Investments	Note 14 – Tax Equity Investments The Company makes investments in the equity of certain limited partnerships or limited liability companies that typically qualify for credit under the Community Reinvestment Act. Certain of these equity investments are associated with affordable housing projects that generate LIHTC and other income tax benefits for the Company. The Company typically accounts for tax equity investments using the proportional amortization method, if certain criteria are met. The election to account for tax equity investments using the proportional amortization method is done so on a tax credit program-by-tax credit program basis. Under the proportional amortization method, the Company amortizes the initial cost of the investment, which is inclusive of any commitments to make future equity contributions, in proportion to the income tax credits and other income tax benefits that are allocated to the Company over the period of the investment. The net benefits of these investments, which are comprised of income tax credits and operating loss income tax benefits, net of investment amortization, are recognized in the income statement as a component of income tax expense. At June 30, 2024 and December 31, 2023, the carrying value of these investments was $81.9 million and $88.8 million, respectively, and are included in other assets in the consolidated statements of financial position. As of June 30, 2024, the Company’s unfunded commitments associated with tax equity investments, which comprise of investments in affordable housing partnerships, were estimated to be paid as follows: (Dollars in thousands) Amount Year Ending December 31, 2024 $ 6,022 2025 12,053 2026 8,516 2027 786 2028 463 Thereafter 2,498 Total unfunded commitments $ 30,338 The following table presents income tax credits and other income tax benefits, as well as amortization expense, associated with investments in qualified affordable housing partnerships where the proportional amortization method of accounting has been applied for the periods indicated.

Accounting Policies [Abstract]
Principles of Consolidation	The consolidated financial statements include the accounts of Pacific Premier Bancorp, Inc. (the “Corporation”) and its wholly owned subsidiaries, including Pacific Premier Bank (the “Bank”) (collectively, the “Company,” “we,” “our,” or “us”). All significant intercompany accounts and transactions have been eliminated in consolidation.
Basis of Financial Statement Presentation	In the opinion of management, the unaudited consolidated financial statements reflect all normal recurring adjustments and accruals that are necessary for a fair presentation of the statement of financial position and the results of operations for the interim periods presented. The results of operations for the six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for any other interim period or the full year ending December 31, 2024. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 Form 10-K”).
Variable Interest Entities	The Company consolidates voting entities in which the Company has control through voting interests or entities through which the Company has a controlling financial interest in a variable interest entity (“VIE”). The Company evaluates its interests in these entities to determine whether they meet the definition of a VIE and whether the Company is required to consolidate these entities. A VIE is consolidated by its primary beneficiary, which is the party that has both (i) the power to direct the activities that most significantly impact the economic performance of the VIE and (ii) a variable interest that could potentially be significant to the VIE. To determine whether or not a variable interest the Company holds could potentially be significant to the VIE, the Company considers both qualitative and quantitative factors regarding the nature, size, and form of the Company's involvement with the VIE. The Company is involved with VIEs through its loan securitization activities and affordable housing investments that qualify for the low-income housing tax credit (“LIHTC”). The Company has determined that its interests in these entities meet the definition of variable interests.
Recently Issued Accounting Pronouncements	Accounting Standards Adopted in 2024 In March 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU” or “Update”) 2023-02, Investments - Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, a consensus of the Emerging Issues Task Force . The amendments in this Update allow the option for an entity to apply the proportional amortization method of accounting to other equity investments that are made for the primary purpose of receiving income tax credits or other income tax benefits, if certain conditions are met. Prior to this Update, the application of the proportional amortization method of accounting was limited to investments in low income housing tax credit structures. The proportional amortization method of accounting results in the amortization of applicable investments, as well as the related income tax credits or other income tax benefits received, being presented on a single line in the statements of income, that is income tax expense. Under this Update, an entity has the option to apply the proportional amortization method of accounting to applicable investments on a tax-credit-program-by-tax-credit-program basis. In addition, the amendments in this Update require that all tax equity investments accounted for using the proportional amortization method use the delayed equity contribution guidance in paragraph 323-740-25-3, requiring a liability be recognized for delayed equity contributions that are unconditional and legally binding or for equity contributions that are contingent upon a future event when that contingent event becomes probable. Under this Update, low income housing tax credit investments for which the proportional amortization method is not applied can no longer be accounted for using the delayed equity contribution guidance. Further, this Update specifies that tax equity investments accounted for using the equity method must apply the impairment guidance in Subtopic 323-10 - Investments - Equity Method and Joint Ventures - Overall. This Update also clarifies that for low income housing tax credit investments not accounted for under the proportional amortization method or the equity method, an entity shall account for them under Topic 321 - Investments - Equity Securities. The amendments in this Update also require additional disclosures in interim and annual periods concerning investments for which the proportional amortization method is applied, including (i) the nature of tax equity investments, and (ii) the effect of tax equity investments and related income tax credits and other income tax benefits on the financial position and results of operations. The provisions of this Update became effective for the Company for interim and annual periods beginning January 1, 2024. Refer to Note 14 – Tax Equity Investments for additional information. The adoption of this Update did not have a material impact on the Company’s consolidated financial statements. Recent Accounting Guidance Not Yet Effective In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures . The FASB issued this Update to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this Update address investor requests for more transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid. The amendments in this Update are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this Update on its consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segments . The amendments in this Update improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis. Amendments in this Update include: a requirement that a public entity provide all annual disclosures about a reportable segment’s profit or loss in its interim period disclosures, disclosure of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), disclosure of amounts for other segment items by reportable segment and a description of its composition, clarification that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit or loss, requires that a public entity disclose the title and position of the CODM, and an explanation of how the CODM uses the reported measure(s) of segment profit or loss, and requires that a public entity that has a single reportable segment provide all the disclosures required by this Update as well as all existing disclosures required in Topic 280. The amendments in this Update are effective for the Company beginning with its 2024 annual financial statement disclosures for the year ended December 31, 2024, and for all interim and annual periods thereafter. Early adoption is permitted. The Company is currently evaluating the impact of this Update.
Use of Estimates	Use of Estimates
Allowance for Credit Losses on Investment Securities and Loans	The Company maintains an ACL for loans and unfunded loan commitments in accordance with ASC 326 - Financial Instruments - Credit Losses . ASC 326 requires the Company to initially recognize estimates for lifetime credit losses on loans and unfunded loan commitments at the time of origination or acquisition. The recognition of credit losses represents the Company’s best estimate of lifetime expected credit losses, given the facts and circumstances associated with a particular loan or group of loans with similar risk characteristics. Determining the ACL involves the use of significant management judgement and estimates, which are subject to change based on management’s ongoing assessment of the credit quality of the loan portfolio and changes in economic forecasts used in the Company’s ACL model. The Company uses a discounted cash flow model when determining estimates for the ACL for commercial real estate loans and commercial loans, which comprise the majority of the loan portfolio, and uses a historical loss rate model for retail loans. The Company also utilizes proxy loan data in its ACL model where the Company’s own historical data is not sufficiently available. The discounted cash flow model is applied on an instrument-by-instrument basis, and for loans with similar risk characteristics, to derive estimates for the lifetime ACL for each loan. The discounted cash flow methodology relies on several significant components essential to the development of estimates for future cash flows on loans and unfunded loan commitments. These components consist of: (i) the estimated probability of default (“PD”), (ii) the estimated loss given default (“LGD”), which represents the estimated severity of the loss when a loan is in default, (iii) estimates for prepayment activity on loans, and (iv) the estimated exposure to the Company at default (“EAD”). The PD and LGD are heavily influenced by changes in economic forecasts employed in the model over a reasonable and supportable period. The Company’s ACL methodology for unfunded loan commitments also includes assumptions concerning the probability an unfunded commitment will be drawn upon by the borrower. These assumptions are based on the Company’s historical experience. The Company’s discounted cash flow ACL model for CRE and commercial loans uses internally derived estimates for prepayments in determining the amount and timing of future contractual cash flows expected to be collected. The estimate of future cash flows also incorporates estimates for contractual amounts the Company believes may not be collected, which are based on assumptions for PD, LGD, and EAD. The EAD is determined by the contractual payment schedule and expected payment profile of the loan, incorporating estimates for expected prepayments and future draws on revolving credit facilities. The Company discounts cash flows using the effective interest rate on the loan. The effective interest rate represents the contractual rate on the loan; adjusted for any purchase premiums, or discounts, and deferred fees and costs associated with an originated loan. The Company has made an accounting policy election to adjust the effective interest rate to take into consideration the effects of estimated prepayments. The ACL for loans is determined by measuring the amount by which a loan’s amortized cost exceeds its discounted cash flows expected to be collected. The ACL for credit facilities is determined by discounting estimates for cash flows not expected to be collected. Probability of Default The PD for investor loans secured by real estate is based largely on a model provided by a third party, using proxy loan information. The PDs generated by this model are reflective of current and expected economic conditions in the commercial real estate market, and how they are expected to impact loan level and property level attributes, and ultimately the likelihood of a default event occurring. This model incorporates assumptions for PD at a loan’s maturity. Significant loan and property level attributes include: loan-to-value ratios, debt service coverage, loan size, loan vintage, and property types. The PD for business loans secured by real estate and commercial loans is based on an internally developed PD rating scale that assigns PDs based on the Company’s internal credit risk grades for loans. This internally developed PD rating scale is based on a combination of the Company’s own historical data and observed historical data from the Company’s peers, which consist of banks that management believes align with our business profile. As credit risk grades change for these loans, the PD assigned to them also changes. As with investor loans secured by real estate, the PD for business loans secured by real estate and commercial loans is also impacted by current and expected economic conditions. The Company considers loans to be in default when they are 90 days or more past due or placed on nonaccrual status. Loss Given Default LGDs for commercial real estate loans are derived from a third party, using proxy loan information, and are based on loan and property level characteristics for loans in the Company’s loan portfolio, such as: loan-to-value ratios (“LTV”), estimated time to resolution, property size, and current and estimated future market price changes for underlying collateral. The LGD is highly dependent upon LTV ratios, and incorporates estimates for the expense associated with managing the loan through to resolution. LGDs also incorporate an estimate for the loss severity associated with loans where the borrower fails to meet their debt obligation at maturity, such as through a balloon payment or the refinancing of the loan through another lender. External factors that have an impact on LGDs include: changes in the index for CRE pricing, GDP growth rate, unemployment rates, and the Consumer Price Index. LGDs are applied to each loan in the commercial real estate portfolio, and in conjunction with the PD, produce estimates for net cash flows not expected to be collected over the estimated term of the loan. LGDs for commercial loans are also derived from a third party that has a considerable database of credit related information specific to the financial services industry and the type of loans within this segment, and is used to generate annual default information for commercial loans. These proxy LGDs are dependent upon data inputs such as: credit quality, borrower industry, region, borrower size, and debt seniority. LGDs are then applied to each loan in the commercial segment, and in conjunction with the PD, produce estimates for net cash flows not expected to be collected over the estimated term of the loan. Historical Loss Rates for Retail Loans The historical loss rate model for retail loans is derived from a third party that has a considerable database of credit related information for retail loans. Key loan level attributes and economic drivers in determining the loss rate for retail loans include FICO scores, vintage, as well as geography, unemployment rates, and changes in consumer real estate prices. Economic Forecasts In order to develop reasonable and supportable forecasts of future conditions, the Company estimates how those forecasts are expected to impact a borrower’s ability to satisfy their obligation to the Bank and the ultimate collectability of future cash flows over the life of a loan. The Company uses macroeconomic scenarios from an independent third party, which are based on past events, current conditions, and the likelihood of future events occurring. These scenarios are typically comprised of: a base-case scenario, an upside scenario, representing slightly better economic conditions than currently experienced and, a downside scenario, representing recessionary conditions. Management periodically evaluates appropriateness of economic scenarios and may decide that a particular economic scenario or a combination of probability-weighted economic scenarios should be used in the Company’s ACL model. The economic scenarios chosen for the model, the extent to which more than one scenario is used, and the weights that are assigned to them, are based on the likelihood that the economy would perform better than each scenario, which is based in part on analysis performed by an independent third party. Economic scenarios chosen, as well as the assumptions within those scenarios, and whether to use a probability-weighted multiple scenario approach, can vary from one period to the next based on changes in current and expected economic conditions, and due to the occurrence of specific events. The Company’s ACL model at June 30, 2024 includes assumptions concerning the interest rate environment, general uncertainty concerning future economic conditions, and the potential for recessionary conditions. The Company currently forecasts PDs and LGDs based on economic scenarios over a two-year period, which we believe is a reasonable and supportable period. Beyond this point, PDs and LGDs revert to their long-term averages. The Company has reflected this reversion over a period of three years in each of its economic scenarios used to generate the overall probability-weighted forecast. Changes in economic forecasts impact the PD, LGD, and EAD for each loan, and therefore influence the amount of future cash flows the Company does not expect to collect for each loan. It is important to note that the Company’s ACL model relies on multiple economic variables, which are used in several economic scenarios. Although no one economic variable can fully demonstrate the sensitivity of the ACL calculation to changes in the economic variables used in the model, the Company has identified certain economic variables that have significant influence in the Company’s model for determining the ACL. These key economic variables include changes in the U.S. unemployment rate, U.S. real GDP growth, CRE prices, and interest rates. Qualitative Adjustments The Company recognizes that historical information used as the basis for determining future expected credit losses may not always, by itself, provide a sufficient basis for determining future expected credit losses. The Company, therefore, considers the need for qualitative adjustments to the ACL on a quarterly basis. Qualitative adjustments may be related to and include, but not be limited to, factors such as: (i) management’s assessment of economic forecasts used in the model and how those forecasts align with management’s overall evaluation of current and expected economic conditions, (ii) organization specific risks such as credit concentrations, collateral specific risks, regulatory risks, and external factors that may ultimately impact credit quality, (iii) potential model limitations such as limitations identified through back-testing, and other limitations associated with factors such as underwriting changes, acquisition of new portfolios, and changes in portfolio segmentation, and (iv) management’s overall assessment of the adequacy of the ACL, including an assessment of model data inputs used to determine the ACL. Qualitative adjustments primarily relate to certain segments of the loan portfolio deemed by management to be of a higher-risk profile or other factors where management believes the quantitative component of the Company’s ACL model may not be fully reflective of levels deemed adequate in the judgement of management. Certain qualitative adjustments also relate to heightened uncertainty as to future macroeconomic conditions and the related impact on certain loan segments. Management reviews the need for an appropriate level of qualitative adjustments on a quarterly basis, and as such, the amount and allocation of qualitative adjustments may change in future periods.
Fair Value Measurement	The fair value of an asset or liability is the exchange price that would be received to sell that asset or paid to transfer that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Company utilizes valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 825 - Financial Instruments , requires disclosure of the fair value of financial assets and financial liabilities, including both those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis and a non-recurring basis. The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value are discussed below. In accordance with ASC Topic 820 - Fair Value Measurement , the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described as follows: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities. 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 instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, prepayment speeds, volatilities, etc.), or model-based valuation techniques where all significant assumptions are observable, either directly or indirectly, in the market. Level 3 - Valuation is generated from model-based techniques where one or more significant inputs are not observable, either directly or indirectly, in the market. These unobservable assumptions reflect the Company’s own estimates of assumptions that market participants would use in pricing the asset or liability. Valuation techniques may include use of matrix pricing, discounted cash flow models, and similar techniques. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature, and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Changes in assumptions could significantly affect the fair values presented. Management uses its best judgment in estimating the fair value of the Company’s financial instruments; however, there are inherent limitations in any estimation technique. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. Management maximizes the use of observable inputs and attempts to minimize the use of unobservable inputs when determining fair value measurements. Estimated fair values are disclosed for financial instruments for which it is practicable to estimate fair value. These estimates are made at a specific point in time based on relevant market data and information about the financial instruments. These estimates do not reflect any premium or discount that could result from offering the Company’s entire holdings of a particular financial instrument for sale at one time, nor do they attempt to estimate the value of anticipated future business related to the instruments. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in any of these estimates. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following is a description of both the general and specific valuation methodologies used for certain instruments measured at fair value, as well as the general classification of these instruments pursuant to the fair value hierarchy. AFS Investment Securities – Investment securities are generally valued based upon quotes obtained from independent third-party pricing services, which use evaluated pricing applications and model processes. Observable market inputs, such as, benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data are considered as part of the evaluation. The inputs are related directly to the security being evaluated, or indirectly to a similarly situated security. Market assumptions and market data are utilized in the valuation models. The Company reviews the market prices provided by the third-party pricing service for reasonableness based on the Company’s understanding of the marketplace and credit issues related to the securities. The Company has not made any adjustments to the market quotes provided by them and, accordingly, the Company categorized these securities within Level 2 of the fair value hierarchy. Equity Securities With Readily Determinable Fair Values – The Company’s equity securities with readily determinable fair values consist of investments in public companies and qualify for CRA purposes. The fair value is based on the closing price on nationally recognized securities exchanges at the end of each period and classified as Level 1 of the fair value hierarchy. Interest Rate Swaps – The Company originates a variable rate loan and enters into a variable-to-fixed interest rate swap with the customer. The Company also enters into an offsetting swap with a correspondent bank. These back-to-back swap agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The Company also enters into interest rate swap contracts with institutional counterparties to hedge against certain fixed-rate loans. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a market standard discounted cash flow approach. The Company incorporates credit value adjustments on derivatives to properly reflect the respective counterparty’s nonperformance risk in the fair value measurements of its derivatives. The Company has determined that the observable nature of the majority of inputs used in deriving the fair value of these derivative contracts fall within Level 2 of the fair value hierarchy, and the credit valuation adjustments are not significant to the overall valuation of its derivative financial instruments. As a result, the valuation of interest rate swaps is classified as Level 2 of the fair value hierarchy. Equity Warrant Assets – The Company acquired equity warrant assets as a result of the acquisition of Opus. The warrants provide the Bank the right to purchase a specific number of equity shares of the underlying company’s equity at a certain price before expiration and contain net settlement terms qualifying as derivatives under ASC Topic 815 - Derivatives and Hedging . The fair value of equity warrant assets is determined using a Black-Scholes option pricing model and are classified as Level 3 within the fair value hierarchy due to the extent of unobservable inputs. The key assumptions used in determining the fair value include the exercise price of the warrants, valuation of the underlying entity's outstanding stock, expected term, risk-free interest rate, marketability discount for private company warrants, and price volatility. During 2023, the equity warrant assets were either settled or written off as the warrants were determined to not be exercisable until the underlying company’s fair market value is greater than the value established in the warrant agreement. Foreign Exchange Contracts – The Company enters into foreign exchange contracts to accommodate the business needs of its customers. The Company also enters into offsetting contracts with institutional counterparties to mitigate the Company’s foreign exchange exposure with its customers, or enters into bilateral collateral and master netting agreements with certain customer counterparties to manage its credit exposure. The Company measures the fair value of foreign exchange contracts based on quoted prices for identical instruments in active markets, a Level 1 measurement. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Individually Evaluated Loans – A loan is individually evaluated for expected credit losses when it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement and it does not share similar risk characteristics with other loans. Individually evaluated loans are measured at fair value when they are deemed collateral dependent. Fair value on such loans is measured based on the underlying collateral. Collateral generally consists of accounts receivable, inventory, fixed assets, real estate, and cash. The Company measures impairment on all individually evaluated loans for which it has reduced the principal balance to the value of the underlying collateral less the anticipated selling costs. Other Real Estate Owned – OREO is initially recorded at the fair value less estimated costs to sell at the date of transfer. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the allowance for credit losses. The fair value of individually evaluated collateral dependent loans and OREO were determined using Level 3 assumptions, and represents individually evaluated loan for which a specific reserve has been established or on which a write down has been taken. For real estate loans, generally, the Company obtains third party appraisals (or property valuations) and/or collateral audits in conjunction with internal analysis based on historical experience on its individually evaluated loans to determine fair value. In determining the net realizable value of the underlying collateral for individually evaluated loans and OREO, the Company then discounts the valuation to cover both market price fluctuations and selling costs, typically ranging from 7% to 10% of the collateral value, that the Company expects would be incurred in the event of foreclosure. In addition to the discounts taken, the Company’s calculation of net realizable value considered any other senior liens in place on the underlying collateral. For non-real estate loans, fair value of the loan’s collateral may be determined using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions, and management’s expertise and knowledge of the client and client’s business.
